Question

How are photosynthesis and cellular respiration related? (1 point)

A) cellular respiration cannot occur without photosynthesis
B) they each occur in completely different organisms
C) both depend on ATP as a source of energy
D) both produce more ATP than they use

Answer 1

The correct option is A.
The photosynthesis process and the cellular process are dependent on each other and one can not occur without the other.
During the photosynthesis process, water and carbon dioxide yield glucose and oxygen while cellular respiration uses glucose and oxygen to produce carbon dioxide and water. Thus, the product of photosynthesis are the reactants of cellular respiration.

Answer 2

1. Used ATP is discarded by the cells as waste

2. Transporting energy within the cell

3. Auto produce organic molecules

4. Both depend on ATP as a source of energy

5. A cactus is moved from a sunny windowsill to a dark room

6. Photosynthesis is the base of energy flow, Because it converts energy from the sun into fuel for plants.
