Unit 4 (For Final Review)

Front

What is the process that transforms light energy into chemical energy in plants?

Back

Photosynthesis

Front

What is the primary purpose of cellular respiration?

Back

To convert chemical energy from glucose into ATP when oxygen is present.

Front

What is lactic acid fermentation and when does it occur?

Back

A process that occurs in muscles when oxygen is scarce, converting glucose into lactic acid.

Front

What is ATP and why is it important?

Back

Adenosine triphosphate (ATP) is the energy currency of the cell, used to power various cellular processes.

Front

Which bond in the ATP molecule is broken to release energy?

Back

The bond between the second and third phosphate groups (Bond A).

Front

What gas is produced during photosynthesis?

Back

Oxygen gas.

Front

What is the role of oxygen in cellular respiration?

Back

Oxygen is used to help convert glucose into ATP.

Front

What are heterotrophs?

Back

Organisms that cannot produce their own food and rely on consuming other organisms for energy.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen, while anaerobic respiration occurs without oxygen.

Front

What is the main byproduct of lactic acid fermentation?

Back

Lactic acid.
