Chemiosmotic theory of ATP synthesis, in the chloroplast and mitochondria, is based on:
1 proton gradient
2 membrane potential
3 accumulation of $\mathrm{K}$ ions
4 accumulation of $\mathrm{Na}$ ions
Explanation:
A Chemiosmotic theory of ATP synthesis, in the chloroplast and mitochondria, is based on proton gradient. The chemiosmotic theory explains how ATP is generated in the mitochondria via the ETC. ETC is an oxidative phosphorylation reaction taking place in the inner membrane of the mitochondria. ATP is generated utilizing the electronchemical gradient generated due to the accumulation of protons in the thylakoid lumen of chloroplast.

Three hexoses are produced as net gain in calvin cycle by the assimilatory power generated in noncyclic photophosphorylation with 36 water molecules. The ratio of $\mathrm{O}_{2}$ released to that of ATP generated is
1 $3: 1$
2 $3: 2$
3 $1: 1$
4 $4: 1$
Explanation:
C In noncyclic photophosphorylation, 2 ATP molecules are produced for every water molecule that is split. So, 36 water molecule will produce 72 ATP molecule. For every 2 water molecules that are split, 1 oxygen molecule is produced. So, 36 water molecules will produce 18 oxygen molecules. So, the ratio of $\mathrm{O}_{2}$ and ATP is $1: 1$.

How many ATP molecules are generated when one molecule of reduced coenzyme $\mathrm{NADH}_{2}$ is reoxidised during respiratory chain ?
1 Two
2 Four
3 One
4 Three
Explanation:
D The $\mathrm{NADH}_{2}$ and the $\mathrm{FADH}_{2}$ are produced during the cycles of respiration. These molecules are produced during the glycolysis and the krebs cycle. These molecules are oxidized in the process of electrons transport system (ETS). These products are oxidized and the protons are used for creating a gradient which is used in the synthesis of ATP. $\mathrm{NADH}_{2}$ transfers the electrons to the complex I to complex II. By this process move number of protons which are pumped by ATP synthase. SO, the more protons will result in production of 3 ATPs.
