6.

There are two types of reactions in photosynthesis: lightdependent reactions and light-independent reactions. A group of biology students creates a set of devices that will automatically measure the rates of both types of reactions. The light-dependent reaction rate is tracked by the rate of water uptake in plants, and the light-independent reaction rate is tracked by the rate of carbon dioxide gas uptake in plants. The students decide to measure the rate of the lightdependent reactions at noon, when the light is brightest, in a sunny room. They measure the rate of the light-independent reactions at 8:00 p.m. in a dark room under very minimal lighting conditions. What is the most obvious critique of the students’ experimental design?

a)

The light-independent reactions are dependent on the products of the light-dependent reactions which do not occur at night or under very low light conditions.

b)

The light-dependent reactions do not require water but rather carbon dioxide gas that is needed for carbon fixation.

c)

The presence of even very low light levels in the room will ensure that the light-independent reactions of photosynthesis will not happen.

d)

The rate of the light-dependent reactions will actually be greater earlier in the morning with more indirect light and milder temperatures.

7.

The light-dependent reactions of photosynthesis involve the use of solar energy to split water molecules. What is the significance of this step in the light-dependent reactions?

a)

It results in the release of oxygen as a waste product.

b)

It provides free electrons for the production of carbon dioxide.

c)

It results in the release of energy by breaking highenergy bonds in ATP.

d)

It forms sugars that are broken down during the lightindependent reactions.

8.

How is the energy produced during photosynthesis converted by cells to provide the energy needed for life processes?

a)

Cells convert the ATP produced during photosynthesis to glucose.

b)

Cells convert the oxygen produced during photosynthesis to glucose.

c)

Cells convert the glucose produced during photosynthesis to carbon dioxide.

d)

Cells convert the glucose produced during photosynthesis to ATP

9.

A runner in a cross country tournament experiences muscle cramps toward the end of the race. After completing the race and resting, the runner’s cramps eventually go away. Which statement best explains what has occurred?

a)

The runner did not sufficiently warm up before the race and experienced cramping as the muscles were forced to convert fat into a useable energy source.

b)

As the runner reached the end of the race, fatigued muscle cells began to die at a rate faster than they could be replicated, which resulted in an increased amount of muscle cramping.

c)

As the runner became more fatigued, the muscles did not receive enough oxygen and were forced to perform anaerobic respiration, resulting in cramping.

d)

The runner did not consume sufficient levels of glucose before the race and experienced cramping because the muscles were forced to increase glucose production.

10.

Which equation best represents the aerobic respiration reaction?

a)

Glucose → Pyruvic Acid + ATP

b)

Pyruvic Acid → Lactic Acid + ATP

c)

Pyruvic Acid + Oxygen → Alcohol + Carbon Dioxide + ATP

d)

Glucose + Oxygen → Carbon Dioxide + Water + ATP

11.

During heavy exercise, a human body uses oxygen to produce energy. When the demand for energy increases further, the body produces the additional energy in an oxygen deficit condition.

a)

to maintain the heat lost by the body during exercise

b)

to produce extra energy that was used up

c)

to replenish the oxygen store that was used up

d)

The researcher prepared four test tubes containing 40 mL of warm water and added 0.5 g, 1.0 g, and 1.5 g of sucrose to Test Tubes 2, 3, and 4, respectively. No sucrose was added to Test Tube 1. The researcher then added 1 g of yeast to all four test tubes.
