The primary energy carrier in cells, composed of adenine, ribose, and 3 phosphate groups.

Enzymes that catalyze the hydrolysis of ATP, releasing energy.

The chemical reaction where ATP is converted to ADP and Pi, releasing energy.

The process of adding a phosphate group to a molecule, often driven by ATP.

The continuous conversion of ATP to ADP and back, maintaining energy supply.

Process that releases energy from food, converting ADP back into ATP.

Process where plants convert sunlight into glucose and oxygen using chloroplasts.

The loss of electrons or gain of oxygen in a chemical reaction.

The gain of electrons or loss of oxygen in a chemical reaction.

Simultaneous oxidation and reduction reactions that occur in cells.

The specific region of an enzyme where the substrate binds and reaction occurs.

Non-protein molecules or ions that assist enzymes in catalyzing reactions.

Sequences of enzymatic reactions that convert substrates into products.

Loss of enzyme structure due to extreme temperature or pH, resulting in loss of function.

Modulation of enzyme activity by binding to a site other than the active site.

End product of a pathway inhibits an enzyme early in the pathway to regulate activity.

Energy cannot be created or destroyed, only transformed or transferred.

A measure of disorder in a system; energy lost as heat increases entropy.

Reactions that release energy and have a negative ΔG, occur spontaneously.

Reactions that require energy input and have a positive ΔG, do not occur spontaneously.

Indicates whether a reaction is spontaneous; ΔG = ΔH - TΔS.

A system where both energy and matter can flow in and out.

A system where energy can flow in or out, but matter cannot.

Processes that involve the transformation of substances, often losing energy as heat.

The study of energy transfer and transformation in physical and chemical processes.

Energy from the sun moves through organisms; some is converted to heat and increases entropy.

Demonstrates open vs. closed systems and how energy behaves in each.

Energy from the sun essential for life and powering photosynthesis.

The process of energy moving from one system to another, usually with some loss as heat.
