Question

Explain how it has stopped the algae from making atp, nadph and sugars.

Answer 1

Answer:

Light energy cannot reach the chloroplasts, preventing ATP and NADPH production by the light-dependent reactions. ... -The LDRs convert small high-energy molecules into sugars, the Calvin cycle converts light energy into chemical energy, and cellular respiration breaks down sugars to produce ATP.

Answer 2

1. Because anoxia inhibits the Calvin-Benson-Bassham (CBB) cycle by preventing respiration and causing decreased ATP levels in green algae, the balance between ATP and NADPH shifts.
2. This imbalance also creates a condition in which NADP+ reduction is not preferred, resulting in acceptor side limitation on PSI.
3. As a result, hydrogenase production at light onset alleviates these constraints and contributes to the formation of a proton gradient, which supports ATP production.
4. As a result, after dark incubation, H2 accumulates quickly upon the onset of light.
5. However, this accumulation only lasts a short time before hydrogenase is inactivated due to a shift in electron flow toward other metabolic pathways.

Hence, this is how algae has stopped from making ATP, NADPH and sugars.
