Question

where do light - independent reactions (calvin cycle) occur within the chloroplast?
a. thylakoid membranes
b. inner mitochondrial membrane
c. stroma
d. cytoplasm

which of the following best summarizes the overall process of photosynthesis?
a. the storage of light energy in the form of glucose and atp
b. the conversion of carbon dioxide and water into glucose and oxygen using light energy
c. the conversion of atp into glucose and oxygen
d. the breakdown of glucose into carbon dioxide and water

what is the relationship between photosynthesis and cellular respiration?
a. photosynthesis and cellular respiration are identical processes.
b. photosynthesis produces glucose and oxygen, which are used in cellular respiration to generate atp.
c. cellular respiration stores energy, while photosynthesis releases it.
d. cellular respiration occurs only in plants, while photosynthesis occurs only in animals.

Explanation:

1. Light - independent reactions (Calvin Cycle) occur in the stroma of the chloroplast. Thylakoid membranes are for light - dependent reactions, inner mitochondrial membrane is related to cellular respiration, and cytoplasm is not the site for Calvin Cycle.
2. Photosynthesis is the process of converting carbon dioxide and water into glucose and oxygen using light energy. It is not about storing light energy in glucose and ATP directly, nor converting ATP to glucose and oxygen, and the breakdown of glucose is cellular respiration.
3. Photosynthesis produces glucose and oxygen which are used as reactants in cellular respiration to generate ATP. They are not identical processes, photosynthesis stores energy while respiration releases it, and cellular respiration occurs in both plants and animals while photosynthesis occurs in plants.

Answer:

1. c. Stroma
2. b. The conversion of carbon dioxide and water into glucose and oxygen using light energy
3. b. Photosynthesis produces glucose and oxygen, which are used in cellular respiration to generate ATP.
