Is ATP produced in both photosynthesis and respiration?

Answer 1

Yes and No. There are two parts of photosynthesis, the light reactions and Calvin cycle. The light reactions produce ATP and NADPH which the Calvin reactions then use to produce sugars.

So yes in respration 32-38 ATP are produced. And yes ATP is made by the light rxns in photosynthesis but is not a final product like the ATP in respiration

Answer 2

In photosynthesis energy stored in ATP is used to make glucose. The steps in photosynthesis is the light dependent reactions (or light reactions) and the light independent reactions (or dark reactions, or Calvin cycle). In cellular respiration, glucose is broken down into ATP. Cellular respiration is made up of three steps or processes: glycolysis, Krebs cycle, and cell transport chain. The products of glycolysis for one glucose molecule is 2 ATP, 2 NADH, and 2 pyruvic acids which are used in the Krebs cycle. The products of Krebs cycle is 1 ATP, 4 NADH, and 1 FADH2 for one pyruvic acid. Since there are 2 pyruvic acids in one glucose, you need to double the products making it 2 ATP, 8 NADH, and 2 FADH2. In the cell transport chain, the FADH2 and NADH is 'traded in' for ATP. In the end one glucose molecule produces 36 ATP molecules.

Answer 3

2 H2O + 2 NADP+ + 3 ADP + 3 Pi + light → 2 NADPH + 2 H+ + 3 ATP + O2

from the light dependent phase of photosynthesis
