AP Bio Prep Review 2: Cells and Cell Processes

Front

What is oxidation?

Back

Loss of electrons.

Front

What process allows water to move into root cells of a plant when the concentration of water is higher in the soil?

Back

Osmosis.

Front

What type of transport involves the movement of molecules across a membrane via a protein channel without energy?

Back

Facilitated diffusion.

Front

In plant cells, where does photosynthesis occur?

Back

Chloroplast.

Front

What is the process called when ATP energy is used to pump sodium out of a cell and potassium into the cell?

Back

Active transport.

Front

Define osmosis.

Back

The movement of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration.

Front

What is facilitated diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are the organelles where photosynthesis occurs, converting light energy into chemical energy.

Front

What is active transport?

Back

The movement of molecules across a cell membrane against their concentration gradient, requiring energy.

Front

What is the difference between simple diffusion and facilitated diffusion?

Back

Simple diffusion does not require a protein and occurs directly through the phospholipid bilayer, while facilitated diffusion requires a protein to help transport molecules.
