Proteins that provide energy to cells.

Chemicals that dissolve fats.

Enzymes are biological catalysts that speed up chemical reactions in living organisms.

Components of DNA that control genetic traits.

Enzymes lower the activation energy required for a reaction to proceed.

Enzymes raise the activation energy needed for a reaction to happen.

Enzymes have no effect on activation energy.

Enzymes neutralize all energy in a reaction.

The active site is the region on an enzyme where the substrate binds and the reaction occurs.

The part of the enzyme that regulates cellular respiration.

A site that produces energy for the enzyme's function.

Where the enzyme releases waste products.

Substrate specificity means that each enzyme can only bind to specific substrate molecules with a complementary shape.

Substrate specificity means enzymes can react with all molecules.

Enzymes react only with sugar substrates.

Enzymes alter their shape to fit any substrate.

Enzymes are often named after the substrate they act on, with the suffix '-ase' added, such as lipase or protease.

Enzymes are named based on the type of cell they are found in.

Enzymes are named after the scientist who discovered them.

Enzymes are named randomly.

Only enzyme concentration affects activity.

Temperature is the only factor.

Enzyme activity can be affected by temperature, pH, enzyme concentration, and substrate concentration.

Time of day primarily affects enzyme activity.

When an enzyme gains new functions.

Denaturation refers to the process where an enzyme loses its structure and, therefore, its function, often caused by high temperatures or extreme pH.

The enhancement of an enzyme's active site.

An increase in enzyme production rate.

Coenzymes are inactive components within enzymes.

Coenzymes provide the primary structure of enzymes.

Coenzymes are organic molecules that bind to enzymes and assist in the enzyme's catalytic reaction, often by acting as carriers for electrons or specific atoms.

Coenzymes store energy for reactions.

No, enzymes are used up after one reaction.

Only in certain chemical reactions.

Yes, enzymes are not consumed in the reaction, so they can be used repeatedly to catalyze multiple reactions.

Only in the presence of light.

Hemoglobin, which carries oxygen in cells.

An example is amylase, which breaks down starch into sugars during digestion.

Vitamins, which support growth and metabolism.

Chlorophyll, which is involved in photosynthesis.

The permanent destruction of an enzyme.

Enzyme inhibition is a process where a molecule binds to an enzyme and decreases its activity.

Increasing enzyme activity by temperature.

A shift in enzyme's pH balance.

A competitive inhibitor is a molecule that competes with the substrate by binding to the active site of the enzyme.

A molecule that enhances enzyme activity.

A natural substrate that reacts faster.

A binding molecule at a distal site.

A molecule that competes at the active site.

A non-competitive inhibitor binds to a site other than the active site, causing a change in enzyme shape and function.

An activator that neutralizes competitive inhibitors.

A substrate that accelerates enzymatic reactions.

Decreases the reaction rate in all conditions.

Has no impact on reaction rate.

Increasing enzyme concentration generally increases the reaction rate, provided there is an excess of substrate available.

Only affects rate at high temperatures.

Enzymes are crucial because they enable metabolic processes to occur quickly and efficiently at body temperatures.

Enzymes store energy for later use.

Enzymes fight against bacterial infections.

Enzymes provide structural support to cells.
