RESPIRATION

Which type of respiration is more efficient?

• Glycolysis

• Kreb's cycle

• Aerobic

• Anaerobic

Where does Glycolysis occur in an animal cell

• Cytoplasm

• Matrix of mitochondrion

• Nucleus

• Ribosome

Which of the following is not a condition required for aerobic respiration?

• Optimum temperature

• Oxygen

• Food substrate such as glucose

• ATP

Identify the below structure

• Kidney

• Nephron

• Mitochondrion

• Mitochondria

Identify the end product of pyruvic acid in animals if no oxygen is available.

• Ethanol and Carbon (IV) oxide

• Ethanol

• Lactic acid

• Carbon (IV) oxide

Which of the following equations leads to the formation of ATP?

• ADP + Phosphate

• ADP + Energy

• ADP + ATP

• ADP + Phosphate + Energy

Which of the following is not the use of energy obtained from respiration?

• Muscle contraction during movement in animals

• Transmission of nerve impulses in animals

• Growth and repair of worn out tissues

• Digging and working

Why is the inner membrane of a mitochondrion highly folded?

• To increase the rate of respiration

• To increase the surface area of the attachment of respiratory enzymes for faster rate of respiration.

• To occupy less space

• For faster diffusion of enzymes

Which of the following is not a reason why Adenosine triphosphate is preferred as an energy storage molecule?

• It cannot pass out of the cell

• Releases energy immediately when broken down.

• It can easily be broken down to release energy.

• It is highly reactive

Which of the following is not an adaptation of mitochondrion to its function?

• It has a double membrane to enclose and protect the internal contents.

• It has respiratory enzymes to catalyze the rate of respiration.

• It has a inner membrane that is greatly folded into cristae to increase surface area for respiration.

• It is rigid thus cannot be affected by high temperatures.
