Enzyme Reactions and Properties

Front

A catalyzed reaction will have lower activation energy and this leads to an increase in the reaction rate.

Back

The presence of a catalyst lowers the energy needed for the reaction.

Front

In the enzyme substrate complex, during step 2, the enzyme is breaking bonds in the substrate.

Back

This step is crucial for the transformation of the substrate into products.

Front

An increase in temperature results in an increase in reaction rate.

Back

Higher temperatures provide more energy to the reactants, increasing their movement and collision frequency.

Front

If a reaction absorbs more energy than it releases, it is endothermic.

Back

Endothermic reactions require energy input to proceed.

Front

The molecule that an enzyme binds to is known as its substrate.

Back

The substrate is the specific reactant that an enzyme acts upon.

Front

Reactants bind to enzymes at the active site.

Back

The active site is the region on the enzyme where the substrate binds.

Front

Chemical reactions that absorb more energy than they release are called endothermic.

Back

These reactions are characterized by a net gain of energy.

Front

Reaction that directly provides chemical energy for most cell functions

Back

ADP + P ⟶ ATP

Front

Energy is released from an ATP molecule when it loses a phosphate group
