AP Biology Unit 2 Review

Front

What is the function of the Golgi Bodies in a cell?

Back

The Golgi Bodies modify, package, and sort proteins and lipids for secretion or delivery to other organelles.

Front

What happens to a cell placed in a hypotonic solution?

Back

The cell will swell as water enters the cell due to osmosis.

Front

What are channel proteins?

Back

Channel proteins are integral membrane proteins that facilitate the transport of ions and molecules across the cell membrane through tunnels.

Front

Define osmosis.

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the role of carrier proteins in facilitated diffusion?

Back

Carrier proteins help transport large or polar molecules across the cell membrane by changing shape.

Front

What is the difference between passive and active transport?

Back

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

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, leading to water entering the cell.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of transporting molecules across a membrane via proteins, without the use of energy.

Front

What is the primary function of the rough endoplasmic reticulum (Rough ER)?

Back

The Rough ER is involved in the synthesis and initial folding of proteins that are to be secreted or sent to the cell membrane.

Front

What is the role of the smooth endoplasmic reticulum (Smooth ER)?

Back

The Smooth ER is involved in lipid synthesis, detoxification, and calcium ion storage.
