D) cellular respiration

2. Photosynthesis consists of which two set of reactions that are linked by redox reactions to generate chemical energy

A) light capturing reactions and splitting water  

B) light capturing reactions and chemiosmosis

C) light capturing reactions and Kelvin cycle

D) light capturing reactions and oxidative phosphorylation

3. The photosynthetic pigments of plant are located in or at the

A) cellular cytoplasm

B) thylakoid membrane

C) stroma

D) apoplast  

4. To date, in all of biology, only Photosystem II is known to use solar energy to

A) provide highly energetic electrons to redox reactions that generate chemical energy

B) to provide energy for chemiosmosis

C) absorb light of a wavelength between 550 and 600 nm

D)  produce oxygen by oxidizing (or splitting) water.

5. Rubisco is

A) the enzyme that fixes CO₂ to RuBP

B) a slow enzyme

C) an enzyme that can catalyze two different reactions

D)  All of the above

Answer 1

1. (D) Cellular respiration

The opposite of photosynthesis is cellular respiration. Cellular respiration is the process in which the energy is needed and this energy is yielded from sugars which were produced during photosynthesis. The reactants of the photosynthesis are same as products of photosynthesis.

2. (A) Light capturing reactions and water splitting

In photosynthesis liggt is used to make products which are further used in cellular respiraion. PS2 captures the sunlight and transfer it to other PS. Water is splitted to provide electrons and protons.

3. (B) Thylakoid membrane

Chlorophyll are the photosynthetic pigments which are present in the thylakoid membrane of chloroplast. Pigment molecules captures sunlight and help plamts making their food.

4. (A) Provide highly energetic electrons to redox reactions that generate chemical energy
