W----------------> X-----------------> Y---------------> Z
E E E3 W > X > Y > Z In the series of enzyme reactions shown above, product Z is able to occupy the active site of enzyme E2. Product Z can therefore first inhibit the production of W E1 X E2 Y 1,100
4
Which of the following is an example of active transport across a membrane?
The movement of water from a nephron into the collecting duct of the kidney The movement of glucose by facilitated diffusion into a liver cell The movement of water from the inside of a cell into a surrounding hypertonic medium The movement of Na+ into a neuron as a nerve impulse is generated The movement of H+ into a thylakoid disc during photosynthesis 1,200
5
may be coupled to the hydrolysis of ATP
Within the cell, many chemical reactions that, by themselves, require energy input (have a positive free-energy change) can occur because the reactions may be coupled to the hydrolysis of ATP take place very slowly take place when the cells are at unusually high temperatures are catalyzed by enzymes are aided by various metal ions that act as catalysts 1,300
6
If plant cells are immersed in distilled water, the resulting movement of water into the cells is called conduction active transport transpiration osmosis facilitated diffusion 1,400
7
How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?
By binding at the active site of the enzyme By changing the shape of the enzyme’s active site By changing the free energy change of the reaction By acting as a coenzyme for the reaction By decreasing the activation energy of the reaction 1,500,P
8
Oxygen consumption can be used as a measure of metabolic rate because oxygen is
necessary for ATP synthesis by oxidative phosphorylation necessary to replenish glycogen levels. necessary for fermentation to take place required by all living organisms required to break down the ethanol that is produced in muscles 2,100
9
Electron transport chain and chemiosmosis
Which of the following directly produces the most ATP per mole of glucose during aerobic cellular respiration? Glycolysis Electron transport chain and chemiosmosis Substrate-level phosphorylation Kreb’s Cycle Alcoholic fermentation 2,200
10
Which of the following statements about mitochondrial chemiosmosis is NOT true?
A proton gradient is established across the inner membrane of the mitochondrion. The potential energy released from the mitochondrial proton gradient is used to produce ATP. The mitochondrial proton gradient provides energy for muscle contraction. Proteins embedded in the inner mitochondrial membrane play an important role in ATP synthesis. Heat energy is required to establish the electron transport chain. 2,300
11
During respiration, most ATP is formed as a direct result of the net movement of
potassium against a concentration gradient protons down a concentration gradient electrons against a concentration gradient electrons through a channel sodium ions into the cell 2,400

In a mesophyll cell of a leaf, the synthesis of ATP occurs in which of the following?
I. Ribosomes II. Mitochondria III. Chloroplasts I only II only III only II and III only I, II, and III 3,300
16
All of the following could reduce the yield of photosynthetic products EXCEPT
lower concentrations of carbon dioxide in the atmosphere increased photorespiration reduced carbon dioxide concentrations in the air spaces of the leaf increased frequency of stomatal openings fewer Calvin cycle enzymes 3,400,P
17
Process found in both photosynthesis and cellular respiration
Process by which O2 is released as a by-product of oxidation-reduction reactions Process by which carbon from CO2 is incorporated into organic molecules Process found in both photosynthesis and cellular respiration 1.

18
The organelle that is a major producer of ATP and is found in both heterotrophs and autotrophs is the chloroplast nucleus ribosome mitochondrion Golgi apparatus 4,100
19
When oxygen is released as a result of photosynthesis, it is a direct by-product of
Reducing NADP + The electron transfer system of photosystem II chemiosmosis The electron transfer system of photosystem I Splitting of water molecules. 4,200
20
Which of the following questions is most relevant to understanding the Calvin cycle?

21
During intense exercise, as skeletal muscle cells switch to fermentation, the human body will increase its catabolism of Fats only Proteins only Fats, carbohydrates, and proteins Fats and proteins only Carbohydrates only 4,400
22
Which of the following statements best describes the relationship between photosynthesis and respiration? Photosynthesis occurs only in plants and respiration occurs only in animals ATP molecules are produced in photosynthesis and used up in respiration Photosynthesis stores energy in complex organic molecules, whereas respiration releases it Respiration is anabolic and photosynthesis is catabolic Respiration runs the biochemical pathways of photosynthesis in reverse 4,500
