Back

A molecule that carries energy within cells.

Front

biomolecule

Back

A molecule that is involved in the maintenance and metabolic processes of living organisms.

Front

Back

A difference in the concentration of a substance across a space.

Front

dehydration synthesis

Back

A chemical reaction that builds up molecules by losing water molecules.

Front

deoxyribose sugar

Back

A sugar derived from ribose by replacing a hydroxyl group with hydrogen, found in DNA.

Front

diffusion

Back

The passive movement of particles from an area of high concentration to an area of low concentration.

Front

DNA/genetic material

Back

The molecule that carries genetic instructions in all living things.

Front

endocytosis

Back

A process by which a cell takes in material by engulfing it with its membrane.
