Question

1. In chloroplasts, the enzyme ATP synthase couples the synthesis of ATP to:

a. the diffusion of protons.

b. the reduction of NADP+.

c. the excitation of chlorophyll.

d. the reduction of chlorophyll

e. the transfer of electrons.

 

2. In the two-dimensional paper chromatography technique used by Calvin and Benson, a substance that ends up in the middle of the paper means that:

         a. it is insoluble in one of the solvents.

         b. it is an impure substance.

         c. it is too large to migrate all the way across the paper.

         d. it migrates roughly half way across the paper in both solvents.

         e. it is a relatively large and charged molecule.

In chloroplasts, an electron being passed down the electron transport chain may have originated from:

  1. photosystem I.
  2. photosystem II.
  3. NADPH.
  4. both a and b.
  5. a, b, and c

If we are able to follow a single electron that has just been ejected from the reactive center of photosystem II, which of the following is a feasible pathway that it could take?

  1. photosystem I, electron transport chain, ferridoxin, NADP reductase.
  2. electron transport chain, photosystem I, ferridoxin, NADP reductase.
  3. photosystem I, ferridoxin, NADP reductase, electron transport chain.
  4. ferridoxin, electron transport chain, photosystem I, NADP reductase.
  5. electron transport chain, ferridoxin, photosystem I, NADP reductase.

Step 1

Since we are entitled to answer only 1st question, we’ll answer the question number 1 as you have not mentioned in which question you need help with. Please resubmit the question and specify the other questions you’d like to get answered.

Step 2

The process by which plants, bacteria, and protists use sunlight as the source of energy to produce glucose by using water and carbon dioxide is termed as photosynthesis. Then, the glucose undergoes glycolysis to form pyruvate, which releases ATP by the process of cellular respiration. In plants, chlorophyll is the pigment that absorbs light energy.

Step 3

During cellular respiration in the photosynthesis process, ATP synthesis by ATP synthase is coupled to the electrochemical gradient, which is created b...
