A nonprotein component of an enzyme that is loosely attached to the protein component is referred to as a(n)

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

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

__________ is the science that analyzes energy changes in a collection of matter.

Cells carry out three major types of work; which of the following involves the synthesis of macromolecules as well as the breakdown of substances for their energy?

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

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

The __________ is the electron donor in a redox reaction.

__________ is the total energy change that accompanies a chemical reaction.

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)

In metabolic channeling,the regulation of metabolic pathways is controlled by the __________ of metabolites and enzymes involved in the pathway.

________ reactions build new organic molecules from smaller inorganic and organic compounds.

Disruption of an enzyme's structure with loss of activity caused by extremes of pH,temperature,or other factors is called _________.

Some endergonic reactions can be made to proceed forward if they are coupled to hydrolysis of one or more of the phosphates of ATP.

One of the components used during photosynthetic electron transport is ferredoxin,a nonheme iron protein.

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

__________ reactions capture energy from the organisms' energy source.
