Answer 1

Answer 33: (a) NADPH

Comments: Net reaction of Calvin cycle photosynthesis is

3CO₂ + 6NADPH + 5H₂O + 9ATP------------------> G3P +2H⁺ + 6NADP+ + 9ADP + 8Pi

G3P = glyceraldehyde-3-phosphate

Answer 34: (a) H₂O

Comments: In electron transport chain of chloroplast in presence of light water molecule (H₂O) break and provide two molecules of electrons to photosystem-II for reduction

                                    H₂O--------------> 2H²⁺ + 2e^- + ½ O₂

Answer 35: (a) True

Comments: In both plant and animal cellular respiration takes place in mitochondria to synthesise ATP from ADP

Answer 36: (a) 6 NADH

Comments: Net reaction of the citric acid cycle from one glucose molecule is

2 Acetyl COA + 6NAD⁺ + 2FAD + 2ADP + 2Pi ----------------> 4CO₂ + 6NADH + 6H⁺ + 2 FADH₂ + 2ATP

In glycolysis breakdown of one molecule of glucose 2 molecules of acetyl, Co-A is produced. So overall from one molecules of glucose produce, 2 molecules of acetyl Co-A and this 2 molecules of acetyl Co-A produce 6 molecules of NADH.

Answer 37: (b) anaerobic cell

Comments: Oxygen is not required (anaerobic) for energy production or breakdown of glucose

Answer 38: (b) Hard, require

Comments: An ATP molecule contains two phosphoanhydride bonds at position β and γ of base adenosine. However, one phosphodiester bond at position α of base adenosine. The breakdowns of these phosphoanhydride bonds are harder and it requires energy.

Answer 39: (c) a Kinase

Comments: Hexokinase and phosphofructokinase require ATP for its reaction in glycolysis pathway.

Answer 40: (b) acetyl Co-A

Comments: Fatty acid beak into acetyl Co-A and the produced acetyl Co-A through TCA cycle produce energy.

Answer 41: (b) 6

Comments: Break down of one glucose molecule produce 2 acetyl Co-A molecules in glycolysis, in citric acid cycle from 2 molecules of acetyl Co-A produce 6 CO₂, 10NADH and 2FADH₂

Answer 42: (d) both b and c

Comments: proton gradient is build-up to generate ATP in both cellular respiration and photosynthesis
