Formative Assessment on Cell Respiration

What is the purpose of cellular respiration?

Answer explanation

The purpose of cellular respiration is to convert biochemical energy from nutrients into adenosine triphosphate (ATP), which cells use for energy to perform various functions necessary for life.

Where does cellular respiration occur within the cell?

Answer explanation

Cellular respiration occurs primarily in the mitochondria of the cell, where glucose is converted into ATP, the energy currency of the cell, through processes like glycolysis, the Krebs cycle, and oxidative phosphorylation.

What is the waste product of cellular respiration?

Answer explanation

The waste products of cellular respiration are carbon dioxide and water. During this process, glucose is broken down to produce energy, releasing carbon dioxide as a byproduct.

In order to produce energy, cells start with glycolysis. If oxygen is NOT present after glycolysis, what process occurs next?

• Electron Transport Chain

• Krebs Cycle

• Fermentation

If oxygen IS present after glycolysis, what process occurs next?

• Electron Transport Chain

• Krebs Cycle

• Fermentation

A process that does NOT require oxygen is known as what?

• Aerobic

• Anaerobic

In glycolysis, glucose is broken into 2 molecules of _____________

Where does the Krebs cycle occur? _________________

Which process produces the largest amount of ATP?

• fermentation

• Krebs Cycle

• ETC

The oxygen required by cellular respiration is reduced and becomes part of which molecule?

• ATP

• CO2

• H20
