AP Bio Energy ATP and Enzymes

Front

The place, other than the active site, where activators and inhibitors bind to an enzyme is called the ________ site.

Back

allosteric

Front

What is the sum of all chemical reactions in a living organism?

Back

metabolism

Front

The total amount of energy in a system is ALWAYS ________.

Back

conserved

Front

When a molecule can occupy the same active site as the substrate, this situation is called __________________.

Back

Competitive inhibition

Front

Which factor related to enzyme activity is depicted by a graph showing an increase in substrate concentration?

Back

Increasing substrate concentration

Front

What is the primary energy currency of the cell?

Back

ATP (Adenosine Triphosphate)

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed.

Front

What is the effect of temperature on enzyme activity?

Back

Enzyme activity typically increases with temperature up to a certain point, after which it decreases due to denaturation.

Front

What is the term for a substance that decreases enzyme activity?

Back

Inhibitor

Front

What is the difference between competitive and non-competitive inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while non-competitive inhibition occurs when an inhibitor binds to an allosteric site, changing the enzyme's shape.
