Unit 2 Cell Structure and Function Review New 2023

Front

What is the function of a mitochondrion?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing ATP through cellular respiration.

Front

What is the primary source of hydrogen ions during photosynthesis?

Back

Water provides hydrogen ions during the process of photosynthesis.

Front

What happens to a red blood cell in fresh water?

Back

A red blood cell will burst because water moves into the cell due to osmotic pressure.

Front

List the three stages of cellular respiration in order.

Back

The three stages of cellular respiration are glycolysis, Kreb's cycle, and electron transport chain (ETC).

Front

What are the components of ATP?

Back

ATP consists of adenine, ribose sugar, and three phosphate groups.

Front

Define osmosis.

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs sunlight, which is essential for the process of photosynthesis.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the purpose of the Kreb's cycle?

Back

The Kreb's cycle generates electron carriers (NADH and FADH2) and ATP through the oxidation of acetyl-CoA.

Front

What is the significance of the electron transport chain?

Back

The electron transport chain is crucial for ATP production, as it uses electrons from NADH and FADH2 to create a proton gradient.
