Unit 1.2 Biomolecules, Enzymes, Cell Transport Review

Front

What is an isotonic solution?

Back

An isotonic solution is one where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is active transport?

Back

Active transport is the process of moving molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy.

Front

What is the monomer of proteins?

Back

The monomer of proteins is amino acids.

Front

What happens during osmosis?

Back

During osmosis, water moves from an area of high concentration to an area of low concentration.

Front

What do land plants store energy in?

Back

Land plants store energy in starch.

Front

What is the product of breaking down starch?

Back

The breakdown of starch produces monosaccharides.

Front

What is a hypotonic solution?

Back

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

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher concentration of solutes compared to the inside of the cell, causing water to leave the cell.

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, typically along the concentration gradient.

Front

What role do enzymes play in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions in the body by lowering the activation energy required.
