1. during photosynthesis, what occurs in the light dependent reactions?

a) carbon dioxide is released.
b) oxygen is released.
c) water molecules are created from hydrogen and oxygen.
d) nadp is produced.

Explanation:

Question 17

Glycolysis leads to either aerobic respiration (with oxygen) or anaerobic respiration (without oxygen). The question mark is the process with oxygen, so aerobic respiration (option C) is correct. Photosynthesis (A) makes glucose, fermentation (B) is anaerobic, chemosynthesis (D) uses chemical energy, not related here.

Photosynthesis in plants converts light energy to chemical energy stored in glucose (B). Option A is a by - product for others, C is cellular respiration, D is impossible as plants don't create sunlight.

The photosynthesis equation is \(6CO_2 + 6H_2O+\text{energy}\to C_6H_{12}O_6 + 6O_2\) (B). A has wrong reactants, C is respiration, D has wrong reactants.

Answer:

C. aerobic respiration
