Unit 2 AP Biology Insta-Review (Cell Structure & Function)

Front

Where does the Krebs Cycle take place?

Back

The Krebs Cycle takes place in the Matrix of the mitochondria.

Front

What is required for active transport?

Back

Active transport requires both energy and a transport protein.

Front

How do you calculate water potential?

Back

Water potential = Pressure potential + Solute potential.

Front

What is the pressure potential if it is 0.2 MPa and the solute potential is -0.6 MPa?

Back

Water Potential = -0.4 MPa.

Front

Is the transport membrane protein specific?

Back

True, transport membrane proteins are specific to certain molecules.

Front

What lipid is commonly found in the cell membrane?

Back

Cholesterol is a lipid found in the cell membrane.

Front

What is the function of the mitochondria?

Back

Mitochondria are responsible for producing ATP through cellular respiration.

Front

Define osmosis.

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the role of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.
