Cell Respiration (CR)

What is the series of metabolic pathways used to break down organic molecules called?

• Photosynthesis

• Cell Respiration

• Fermentation

• Glycolysis

Cell respiration converts stored energy from organic molecules into the energy of ____.

• ATP

• Glucose

• NADH

• FADH2

Which type of respiration occurs in the presence of oxygen?

• Anaerobic respiration

• Aerobic respiration

• Fermentation

• Photosynthesis

Which type of respiration is much more efficient and preferred by most organisms?

Muscle cells will utilize anaerobic respiration for quick ________.

• energy production

• oxygen supply

• carbon dioxide removal

• glucose storage

Anaerobic respiration can be used when the supply of ________ is depleted.

• oxygen

• carbon dioxide

• nitrogen

• hydrogen

A cell would want to synthesize ATP because:

• it needs energy for various cellular processes.

• it wants to store genetic information.

• it needs to replicate DNA.

• it wants to produce proteins.
