Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce oxygen and energy in the form of glucose. It occurs in the chloroplasts of plant cells, where chlorophyll absorbs sunlight and uses it to convert carbon dioxide and water into oxygen and glucose. This process provides nutrients and oxygen for other organisms while storing energy in organic molecules.

photosynthesis and respiration
Photosynthesis is the process by which plants capture light energy from the sun to convert carbon dioxide and water into glucose and oxygen. The chloroplasts in leaves contain chlorophyll which absorbs sunlight to drive the photosynthesis reaction. Carbon dioxide enters leaves through stomata and water is absorbed by roots. Oxygen is released as a byproduct through the stomata. Glucose produced is used by the plant for energy and growth or is stored as starch or oils. Respiration uses glucose and oxygen to produce energy for plant functions, releasing carbon dioxide and water.

Photosynthesis 1
Photosynthesis uses light energy, carbon dioxide, and water to produce oxygen and energy-rich organic compounds like glucose. It occurs in two stages - the light-dependent reactions where light energy is captured to make ATP and NADPH, and the light-independent reactions where CO2 is incorporated into organic compounds through the Calvin cycle. Chloroplasts contain chlorophyll and other pigments that absorb light for use in the photosystems. The energy from light drives electron transport and chemiosmosis to produce ATP, then electrons are transferred to NADP+ to form NADPH. These products fuel the Calvin cycle to reduce CO2 into glucose using the energy from ATP and NADPH.

Waste management
The document discusses various aspects of waste management, including definitions of waste and waste management. It describes different types of waste such as solid waste and liquid waste. For solid waste, it covers classification, collection methods, and disposal methods such as composting, recycling, and landfilling. For liquid waste, it discusses sources and types, and technological options for disposal at the household level including kitchen gardens with and without piped root zone systems.
Glycolysis
Glycolysis is the first stage of respiration, where glucose is broken down into two pyruvate molecules. It occurs in two steps: first, glucose is phosphorylated using ATP to form glucose-6-phosphate; second, the glucose-6-phosphate is oxidized to form two pyruvate molecules, producing a net gain of two ATP molecules. The pyruvate molecules then enter the mitochondria for the link reaction, where they are converted into two acetyl CoA molecules to enter the Krebs cycle, with carbon dioxide and NADH also produced.
Glycolysis
1. Glycolysis is the pathway where glucose is broken down to pyruvate with production of ATP. It takes place in the cytosol of cells.
2. Key steps include phosphorylation of glucose to glucose-6-phosphate by hexokinase, isomerization to fructose-6-phosphate, phosphorylation of fructose to fructose-1,6-bisphosphate, cleavage to two 3-carbon molecules, conversion of one to glyceraldehyde-3-phosphate and isomerization, oxidation and phosphorylation to 1,3-bisphosphoglycerate, substrate-level phosphorylation to form ATP, and generation of pyruvate from phosphoenolpyruvate.

Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, water and carbon dioxide to produce oxygen and energy in the form of glucose. It occurs in two stages - the light-dependent reactions where sunlight is absorbed to make ATP and NADPH using chlorophyll, and the light-independent Calvin cycle where carbon is fixed into sugars like glucose using ATP and NADPH. Photosynthesis provides food for plants and oxygen for other organisms while consuming carbon dioxide.
Photosynthesis notes
Photosynthesis is the process by which plants produce their own food, using water, carbon dioxide, and sunlight as raw materials. The byproducts are oxygen and sugars. It occurs in the chloroplasts of plant cells, specifically the mesophyll cells of leaves. Chlorophyll in the chloroplasts absorbs sunlight to drive the reaction that produces oxygen and sugars like glucose. Photosynthesis provides food for heterotrophs and oxygen for all organisms on Earth.

Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, water and carbon dioxide to produce oxygen and energy in the form of glucose. Chlorophyll in the leaves absorbs sunlight which is converted to chemical energy through a series of reactions. Oxygen is released as a byproduct. Glucose is temporarily stored as starch in leaves and is later transported and stored in other plant tissues like fruits and roots. The starch can be tested for using iodine, which turns blue or dark purple in the presence of starch. Sunlight, water, carbon dioxide and chlorophyll are essential for photosynthesis. Human dependence on fossil fuels has increased carbon dioxide levels, trapping heat and warming the planet.

Plants don't go to Coto
Van Helmont conducted an experiment where he planted a willow sapling in soil and measured the soil weight before and after 5 years of growth. He found that the tree had gained 74kg in weight but the soil had only lost 52g. This showed that the tree's food came from water alone, not the soil. However, he overlooked the role of carbon dioxide from the air, which plants use along with water during photosynthesis to produce their own food in the form of glucose.
Nutrition in plants (class vii)
Plants and some bacteria are autotrophs, meaning they can produce their own food using photosynthesis. During photosynthesis, autotrophs use carbon dioxide, water, and energy from sunlight to produce oxygen and carbohydrates like glucose. These carbohydrates provide energy and nutrients for the autotroph. Animals and other organisms are heterotrophs because they cannot produce their own food and rely on autotrophs or other organisms for nutrients. Heterotrophs obtain nutrients by eating autotrophs and other organisms. Humans and other animals eat food to get nutrients and energy from carbohydrates, fats, proteins, vitamins, and minerals which are used to power life processes and allow growth.

Life processes Part 1 (Nutrition)
Living things carry out life processes like nutrition, which can occur through autotrophic or heterotrophic means. Autotrophs like plants perform photosynthesis, using chlorophyll, carbon dioxide, water and sunlight to produce their own food in the form of carbohydrates. Heterotrophs obtain nutrition from other organisms and include animals, fungi and saprophytes. Experiments showed only the green parts of variegated leaves produced starch from photosynthesis, and that carbon dioxide is required for photosynthesis to take place. The human digestive system breaks down starch using salivary amylase in the mouth.

Plants use photosynthesis to convert carbon dioxide and water into glucose and oxygen using sunlight as an energy source. Chlorophyll, the green pigment in leaves, absorbs sunlight and powers this process. Glucose provides energy and carbon that plants use to grow, while oxygen is released as a byproduct. All life depends on photosynthesis as the basis of food webs.

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...
Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

Magmatic iron-meteorite parent bodies are the earliest planetesimals in the Solar System,and they preserve information about conditions and planet-forming processes in thesolar nebula. In this study, we include comprehensive elemental compositions andfractional-crystallization modeling for iron meteorites from the cores of five differenti-ated asteroids from the inner Solar System. Together with previous results of metalliccores from the outer Solar System, we conclude that asteroidal cores from the outerSolar System have smaller sizes, elevated siderophile-element abundances, and simplercrystallization processes than those from the inner Solar System. These differences arerelated to the formation locations of the parent asteroids because the solar protoplane-tary disk varied in redox conditions, elemental distributions, and dynamics at differentheliocentric distances. Using highly siderophile-element data from iron meteorites, wereconstruct the distribution of calcium-aluminum-rich inclusions (CAIs) across theprotoplanetary disk within the first million years of Solar-System history. CAIs, the firstsolids to condense in the Solar System, formed close to the Sun. They were, however,concentrated within the outer disk and depleted within the inner disk. Future modelsof the structure and evolution of the protoplanetary disk should account for this dis-tribution pattern of CAIs.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Summary of photosynthesis
- 1. Summary of Photosynthesis • By Anando Neethling
- 2. WHAT IS PHOTOSYNTHESIS? The process that occurs in green plants, whereby solar energy is converted into chemical energy and stored as organic molecules by making use of carbon dioxide, sunlight, and water. Water and Oxygen are formed as byproducts. Photosynthesis can be summarized in the following equation: 6 CO2 + 12 H2O + Light energy C6H12O6 + 6 O2 + 6 H2O (glucose)
- 3. WHO OR WHAT CAN PHOTOSYNTHESIZE? Photoautotrophs can photosynthesize. Include: Green plants, algae, cyanobacteria and green protists. Plants Green protistsAlgae
- 4. WHY DO PLANTS PHOTOSYNTHESIZE? To provide nutrients and oxygen for heterotrophs. Heterotrophs are dependent on autotrophs, because they cannot produce there own food.
- 5. WHAT PART OF THE PLANT IS RESPONSIBLE FOR PHOTOSYNTHESIS? Photosynthesis occurs in the chloroplasts of plant cells. The chloroplasts are mainly concentrated in the mesophyll cells of leaves. Chloroplast contain chlorophyll – green pigment that absorbs sunlight. Chlorophyll fill the space in the thylakoid membrane.
- 8. The Importance of Photosynthesis Energy entering chloroplasts as sunlight gets stored as chemical energy in organic compounds Sugar made in the chloroplasts supplies chemical energy and carbon skeletons to synthesize the organic molecules of cells. Plants store excess sugar as starch in structures such as roots, tubers, seeds, and fruits In addition to food production, photosynthesis produces the O2 in our atmosphere
