Enzymes catalyze a reaction by

If an enzyme consists of a protein component and a non-protein component, the protein component is referred as the

The molecules formed by an enzyme-catalyzed reaction are called __________.

Enzymes increase the rate of a reaction but do not alter equilibrium constants.

Cells carry out three major types of work; which of the following involves energy for cell motility and the movement of structures within cells?

Electron transport molecules that only transfer electrons include

Enzyme activity can be controlled by

Enzymes increase the rate of a reaction by increasing molecular motion, thereby providing kinetic energy to drive the reaction.

A(n) _______________ increases the rate of a reaction without being permanently altered by the reaction.

The change in __________ is the amount of energy in a system that is available to do work.

The __________ law of thermodynamics states that energy can be neither created nor destroyed.

The most specific term usually used to describe a substance in a biological system that increases the rate of a reaction without being permanently changed by the reaction is a(n)

The standard reduction potential of a redox reaction is a measure of the tendency of the __________ to __________ electrons.

Which of the following is not true about enzymes?

Isoenzymes are different enzymes that catalyze the same reaction but can be regulated independently of one another.

The __________ is the electron donor in a redox reaction.

In thermodynamic studies, energy changes are analyzed in a collection of matter called a __________. All other matter in the universe is called the __________.

The nonprotein component of an enzyme that is firmly attached to the protein is called a(n)

When the end product of a pathway inhibits catalysis of the first step of that pathway, this phenomenon is called

The amount of heat energy needed to raise 1 gram of water from 14.5 $\degree$ C to 15.5 $\degree$ C is called a(n)
