Third set of 18 -- Chapter 4

Which of the following sequences accurately represents the flow of electrons during photosynthesis?

a) H2O → NADPH → Calvin cycle

Cellular respiration is the process by which:

a) energy from the chemical bonds of food molecules is captured by an organism.

During the Calvin cycle, rubisco's function is to:

a) fix carbon to RuBP (ribulose bisphosphate).

Aerobic bacteria:

a) lack mitochondria.

During C4 photosynthesis:

a) plants are able to continue producing sugars even when they must close their stomata to reduce water loss during hot days.

The most abundant protein in the world is the enzyme that initiates the fixation of carbon in the Calvin cycle. This enzyme is called:

a) rubisco.

Which of the following would be a typical product of the dark reactions of photosynthesis?

b) 3-phosphoglycerate acid (3-PGA)

The three different known biochemical pathways organisms will use to photosynthesize include which of the following?

b) C3, C4, CAM

Which of the following statements about glycolysis is INCORRECT?

b) It requires oxygen.

Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which _______________ converts to ATP, the "fuel" used by all living things.

b) cellular respiration

Glycolysis:

e) occurs in all cells.

Where does the Calvin cycle take place?

b) in the stroma of the chloroplast

How many rotations of the Calvin cycle are required for the production of one glucose molecule?

c) 6

To synthesize one glyceraldehyde 3-phosphate (G3P) molecule, the Calvin cycle has to fix three atoms of carbon from carbon dioxide to an organic molecule within the chloroplast. This process consumes how many molecules of ATP and NADPH, respectively, which were generated in the "photo" reactions?

c) 9, 6

The C4 mechanism of carbon fixation is an advantage for plants that live in:

c) hot, dry climates.

The outputs of cellular respiration are:

d) carbon dioxide, water, and ATP.

The ultimate result of glycolysis is two molecules of:

d) pyruvate.

Which of the following does NOT occur during the Calvin cycle?

d) splitting of water
