Photosynthesis, Cellular Respiration, and Enzymes Flashcards

Front

ATP (adenosine triphosphate)

Back

A molecule found in all living cells that provides energy for cellular processes.

Front

Carbon dioxide (CO2)

Back

A chemical compound in gaseous form consumed during photosynthesis and released during cellular respiration.

Front

Cellular process

Back

Any process at the cellular level, such as photosynthesis, cellular respiration, DNA replication, cell division, cell transport, or protein synthesis.

Front

Cellular respiration

Back

A set of metabolic reactions converting chemical energy from glucose into ATP, releasing carbon dioxide and water as waste.

Front

Conservation of energy

Back

The scientific law stating energy cannot be created or destroyed, only changed from one form to another.

Front

Conservation of matter

Back

The scientific law stating matter cannot be created or destroyed, but can change shape or form or atoms can be rearranged to form new compounds.

Front

Consumer

Back

An organism that cannot produce its own food and must obtain energy by eating other organisms.

Front

Glucose (C6H12O6)

Back

A six-carbon sugar, main type of sugar in the blood, major energy source for cells; product of photosynthesis and reactant of cellular respiration.

Front

Oxygen (O2)

Back

A gas consumed during cellular respiration and released during photosynthesis.

Front

Photosynthesis

Back

The chemical process by which plants and other photosynthetic organisms produce glucose using sunlight to convert carbon dioxide and water into oxygen and glucose.
