Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

16. BLACK HOLes (pt1)
When Albert Einstein developed his relativity theory he saw
something very strange in his equations something that could
posses infinite gravity, something that could stop time and even
destroy space itself but he refused to believe something that
strong
could exist, but it DOES !!
A black hole is a actually a super large mass contained in a very
tiny space that it becomes heavy on space-time so much it
deforms it, it’s a hole in the fabric of reality and is considered an
ideal black body which absorbs all light coming.
17. BLACK HOLes (pt2)
we should mention that any matter can be turned into a
black hole for example if we wanted to make a black hole
using the earth we would have to crush it and compress it into
a tiny size of a peanut.
Sagittarius A: the supermassive
black hole at the heart of the
Milky Way Galaxy. It lies in the
direction of the constellation
Sagittarius. This black hole
contains the mass of about
4 million suns.
18. Far away from earth
The Diamond Planet
• 55 Cancri e is an entire planet made out of diamond.
19. Far away from earth
The Vision of Hell
• Kepler-10b it orbits so closely to its sun that the surface is a
vision of hell
• It’s got an ocean bigger than the specific ocean, but its an
ocean not of water , of Lava.
20. Far away from earth
Large Quasar Group
• Quasar is a compact region in the center of a massive galaxy,
that surrounds its central supermassive black hole. It rips
whole stars and devours them, lost forever from the visible
universe or at least from our universe ….
21. Far away from earth
Castor System
• With six stars orbiting around a central mass, this system is
over 54 times as bright as our sun.
22. Far away from earth
The Planet of Burning Ice
• it’s 439 degrees celcius on Gliese 436 b, it’s watery surface
doesn’t evaporate. Instead, the molecules pull together to
form something known as “hot ice”.
• The only reason this ice stays solid is because of the huge
amount of water present
on the planet; the gravity
pulls it all in towards the
core, keeping the water
molecules so densely
packed that they
cannot evaporate.
Editor's Notes
We live inside the sun : the sun’s outer atmosphere extends far beyond its visible surface.
