Removing a phosphate group from ATP to make ADP _________ energy. releases
Organisms that produce their own food are called Autotrophs or producers
Organisms that have to consume food for energy are called Heterotrophs or consumers
What are the reactants of cellular respiration? oxygen and glucose
What are the reactants of photosynthesis? carbon dioxide, water, and energy
What are the products of cellular respiration? carbon dioxide, water, and energy
What are the products of photosynthesis? oxygen and glucose
Photosynthesis takes place in the chloroplast
Cellular respiration takes place in mitochondria
1st step of photosynthesis - requires light energy to split water into oxygen gas and hydrogen atoms. Light-Dependent Reactions
2nd step of photosynthesis - uses ATP as its source of energy to add hydrogen atoms to carbon dioxide and make glucose. Calvin Cycle
The initial source of energy for most communities is sunlight.
The energy released from ATP breaking down into ADP is used to perform cellular work & life functions.
