about the same amount of energy as a carbohydrate
A few types of organisms do not need sunlight and photosynthesis as a source of energy. Some organisms live in places that never get sunlight. In chemosynthesis, chemical energy is used to build carbon-based molecules. similar to photosynthesis uses chemical energy instead of light energy
KEY CONCEPTThe overall process of photosynthesis produces sugars that store chemical energy.
Photosynthetic organisms are producers. Producers make their own source of chemical energy. Plants use photosynthesis and are producers. Photosynthesis captures energy from sunlight to make sugars.
chloroplast leaf cell leaf Chlorophyll is a molecule that absorbs light energy.
In plants, chlorophyll is found in organelles called chloroplasts.
grana (thylakoids) chloroplast stroma Photosynthesis in plants occurs in chloroplasts. Photosynthesis takes place in two parts of chloroplasts. grana (thylakoids) stroma
The light-dependent reactions capture energy from sunlight.
use energy to build a sugar in a cycle of chemical reactions

KEY CONCEPT Photosynthesis requires a series of chemical reactions.
The first stage of photosynthesis captures and transfers energy. The light-dependent reactions include groups of molecules called photosystems.

The Krebs cycle transfers energy to an electron transport chain. takes place inmitochondrial matrix breaks down three-carbonmolecules from glycolysis Krebs Cycle
The equation for the overall process is: C6H12O6 + 6O2 6CO2 + 6H2O
The reactants in photosynthesis are the same as the products of cellular respiration.
KEY CONCEPT Cellular respiration is an aerobic process with two main stages.
Glycolysis is needed for cellular respiration. The products of glycolysis enter cellular respiration when oxygen is available. two ATP molecules are used to split glucose four ATP molecules are produced
The electron transport chain is the second main part of cellular respiration. The electron transport chain uses NADH and FADH2 to make ATP. high-energy electrons enter electron transport chain energy is used to transport hydrogen ions across the inner membrane hydrogen ionsflow through achannel in themembrane
The electron transport chain is the second main part of cellular respiration.
The electron transport chain uses NADH and FADH2 to make ATP.
The breakdown of one glucose molecule produces up to38 molecules of ATP.
