Cell Energy and Enzyme Crossword Puzzle

Across
the type of energy that refers to the potential to do work
describes the pathway in which complex molecules are broken down into simpler ones, yielding energy as an additional product of the reaction
the energy transferred from one system to another that is not work
describes a chemical reaction that results in products that store more chemical potential energy than the reactants
the science of the relationships between heat, energy, and work
The ____ percent rule states that only a set amount not the whole amount of energy is transferred o the next trophic level
a general mechanism of enzyme activity regulation in which a molecule other than the enzyme’s substrate is able to bind the active site and prevent the substrate itself from binding, thus inhibiting the overall rate of reaction for the enzyme
Which phosphate group breaks off of the ATP molecule in phosphorylation
describes the pathway that requires a net energy input to synthesize complex molecules from simpler ones
Protein molecule used to speed up chemical reactions, also considered a biological catalyst
the amount of initial energy necessary for reactions to occur
Nonprotein helper molecule that bind to an active site and function in catalysis, is an organic molecule, empales include vitamins
Which law of thermodynamics is considered the law of energy conservation?
The conditions under which enzymes work best in and are most effective
What is the five carbon sugar found in ATP
Down
An example of an exergonic reaction
the cell’s energy currency
Process of adding a phosphate group to another molecule
all the chemical reactions that take place inside cells, including those that use energy and those that release energy
A form of potential energy and powers the work of the cell
describes a chemical reaction that results in products with less chemical potential energy than the reactants, plus the release of free energy
a specific region on the enzyme where the substrate binds
A series of chemical reactions that either build a complex molecule or breakdown a complex molecule
a general mechanism of enzyme activity regulation in which a regulatory molecule binds to a site other than the active site and prevents the active site from binding the substrate; thus, the inhibitor molecule does not compete with the substrate for the active site; allosteric inhibition is a form of noncompetitive inhibition
An example of an endergonic reaction
the type of energy associated with objects in motion
Enzymes works as biological catalyst by _________ the activation energy
Type of kinetic energy, can be harnessed to power chemical reactions
Nonprotein helper molecule that bind to an active site and function in catalysis, usually inorganic molecules like zinc
