Unit 3 Vocab

Front

ATP

Back

Usable energy for the cell. High energy-carrying molecule, Adenosine Triphosphate.

Front

ADP

Back

Potential to become ATP. Low energy-carrying molecule, Adenosine Di-Phosphate.

Front

Chemosynthesis

Back

Chemical energy is converted into carbohydrates for the organism's food.

Front

Photosynthesis

Back

The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Front

Chlorophyll

Back

A pigment present in all green plants and a few other organisms that absorbs energy from the sun. It is required for photosynthesis.

Front

Thylakoid

Back

Membrane-bound compartment inside the chloroplast. Light-dependent reactions take place here.

Front

Light-Dependent Reaction

Back

Reaction that takes place in sunlight. Light is converted to chemical energy during this reaction. Also known as the Krebs Cycle.

Front

Light-Independent Reaction

Back

Reactions that are not required to occur in sunlight. Uses stored chemical energy to create a product that can be converted into glucose. Also known as the Calvin Cycle.

Front

Photosystem

Back

A mechanism in the thylakoids of plants that are responsible for performing light-dependent reactions.

Front

Electron Transport Chain

Back

A cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons which creates ATP.
