Unit 1,2,3 & 4 Vocab Review

Front

What is an enzyme?

Back

A protein that acts as a catalyst to speed up chemical reactions in the body by lowering the activation energy.

Front

Why do enzymes only affect specific types of bacteria?

Back

An enzyme can only bind to specific molecules with a specific shape.

Front

What are the two types of biomolecules found in both viruses and prokaryotic cells?

Back

Nucleic acids and proteins.

Front

What is active transport?

Back

The movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What role does the hormone auxin play in plants?

Back

Auxin promotes cell elongation on the shaded side of the plant, causing it to bend toward light.

Front

What is interphase?

Back

The phase of the cell cycle where the cell prepares for division by growing, metabolizing, and replicating DNA.

Front

What is diffusion?

Back

The passive movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Back

The diffusion of water molecules through a selectively permeable membrane.

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 function of nucleic acids?

Back

Nucleic acids, such as DNA and RNA, store and transmit genetic information.
