Biology A: Unit 5 Exam

What is the relationship between the digestive system and respiration?

The digestive system breaks food down into the molecules that can be used in respiration.

The role of respiration is to transform the energy from food molecules into usable energy for the cell through a series of chemical reactions.

True

Study the equation. X + Oxygen →→ Y + Water + Energy Which option correctly replaces X and Y, completing the chemical equation for aerobic respiration?

X: Glucose Y: Carbon Dioxide

X produces a fairly Y amount of ATP. Its products are carried to the Z to extract more energy. Which option replaces the letters X, Y, and Z to correctly complete the two statements?

X: Glycolysis Y: low Z: mitochondria

Which option correctly replaces the letters X and Y? A(n) X will bind to the Y of an enzyme so that the chemical reaction can occur.

X: substrate Y: active site

What must a phenylketonuria patient leave out of his or her diet?

When muscle cells lack oxygen but need to generate more ATP, what do they convert pyruvate into?

lactic acid

What are the two types of fermentation?

lactic acid fermentation and alcoholic fermentation

When a biochemical reaction occurs, what is the chemical substance that results?

product

During the citric acid cycle, some carbon atoms are released. What are these carbon atoms released as?

CO2

Which statements are true about glycolysis? Select all that apply.

It converts glucose into pyruvate. It produces NADH. It occurs in the cytoplasm of the cell.

Which statements accurately describe the electron transport chain? Select all that apply.

It uses electrons released from NADH and FADH2. It produces water and a high amount of ATP.

Which substances are produced in the citric acid cycle and fuel the next step in aerobic respiration?

NADH and FADH2

When there is available oxygen in the environment, how many ATP molecules can the ETC produce from a glucose molecule?

38 and 36 are wrong
