Biology Semester 1 Review

Front

What is Active Transport?

Back

A process that requires energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration.

Front

What is Exocytosis?

Back

A type of active transport where materials are expelled from a cell through vesicles that fuse with the cell membrane.

Front

What determines the information in a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What phase of the cell cycle is Anaphase?

Back

Anaphase is the stage in mitosis where sister chromatids are pulled apart to opposite poles of the cell.

Front

What biomolecules provide quick energy and help build muscle?

Back

Carbohydrates and Proteins.

Front

What is Facilitated Diffusion?

Back

A passive transport process that uses transport proteins to move molecules across the cell membrane without energy.

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What are Biomolecules?

Back

Large molecules essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the function of Carbohydrates?

Back

To provide energy and structural support in cells.

Front

What is the role of Proteins in the body?

Back

Proteins serve as building blocks for tissues, enzymes, and hormones.
