ac va on energy
the minimum amount of energy required to start a chemical reac on
ac ve site
The site on an enzyme that a aches to a substrate.
ac ve transport
energy-requiring process that moves material across a cell membrane against a concentra on
difference
ADP
A molecule composed of adenosine and two phosphate groups. The molecule ATP is made by
combining a molecule of ADP with a third phosphate in an energy-consuming reac on.
ATP
A molecule composed of adenosine and three phosphate groups; the main energy source for
cells.
calorie
The amount of energy that raises the temperature of 1 g of water by 1°C.
chemical energy
Energy stored in the chemical bonds of molecules; a form of poten al energy.
concentra on gradient
An increase or decrease in the density of a chemical substance within a given region. Cells o'en
maintain concentra on gradients of hydrogen ions across their membranes. When a gradient
exists, the ions or other chemical substances involved tend to move from where they are more
concentrated to where they are less concentrated.
conserva on of energy
, The principle that energy can neither be created nor destroyed.
diffusion
The spontaneous movement of par cles of any kind down a concentra on gradient; that is,
movement of par cles from where they are more concentrated to where they are less
concentrated.endocytosis
endocytosis
The movement of materials into the cytoplasm of a cell via vesicles or vacuoles.
Energy
The capacity to perform work, or to move ma er in a direc on it would not move if le' alone.
Entropy
A measure of disorder, or randomness. One form of disorder is heat, which is random molecular
mo on.
enzyme inhibitors
A chemical that interferes with an enzyme's ac vity by changing the enzyme's shape, either by
plugging up the ac ve site or binding to another site on the enzyme.
enzymes
A protein that serves as a biological catalyst, changing the rate of a chemical reac on without
itself being changed in the process.
exocytosis
The movement of materials out of the cytoplasm of a cell via membranous vesicles or vacuoles.
facilitated diffusion
The passage of a substance across a biological membrane down its concentra on gradient,
aided by specific transport proteins.
feedback regula on
A method of metabolic control in which the end product of a metabolic pathway acts as an
inhibitor of an enzyme within that pathway.
hypertonic
In comparing two solu ons, referring to the one with the greater concentra on of solutes.
