Biology 1010 Exam 2
Exam Coverage
Exam coverage for the Biology 1010 Exam 2 includes the
fundamental concepts of cell biology, genetics, molecular
biology, evolution, and organismal biology typically covered
during the second portion of an
introductory biology course. It focuses on cellular structure and
function, membrane transport, enzymes, cellular respiration,
photosynthesis, cell
communication, and energy transformation. The exam also evaluates
understanding of DNA structure and function, gene expression,
protein synthesis, cell division, inheritance patterns, and the
molecular basis of heredity.
active site
The site on an enzyme that attaches to a substrate.
active transport
energy-requiring process that moves material across a cell
membrane against a concentration 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 reaction.
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
potential energy.
concentration gradient
An increase or decrease in the density of a chemical substance
within a given region. Cells often maintain concentration
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.
conservation of energy
The principle that energy can neither be created nor destroyed.
,diffusion
The spontaneous movement of particles of any kind down a
concentration gradient; that is, movement of particles 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 matter in a direction it
would not move if left alone.
Entropy
A measure of disorder, or randomness. One form of disorder is
heat, which is random molecular motion.
, enzyme inhibitors
A chemical that interferes with an enzyme's activity by changing
the enzyme's shape, either by plugging up the active site or
binding to another site on the enzyme.
enzymes
A protein that serves as a biological catalyst, changing the rate of
a chemical reaction 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
concentration gradient, aided by specific transport proteins.
feedback regulation
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 solutions, referring to the one with the greater
concentration of solutes.
