Term
cellular respiration?
Definition
the process of making ATP by breaking down organic compounds.
Term
glycolysis?
Definition
the biochemical pathway in which one 6-carbon molecule of glucose is oxidized to produce two 3-carbon molecules of pyruvic acid.
Term
lactic acid fermentation?
Definition
an enzyme converts pyruvic acid made in glycolysis into another 3-carbon compound (lactic acid).
Term
alcoholic fermentation?
Definition
process to convert pyruvic acid into ethyl alcohol.
Term
glycolysis occurs in the ________.
Definition
cytosol.
Term
during glycolysis, glucose is...
Definition
converted into 2 molecules of ATP.
Term
both lactic acid and alcoholic fermentation produce...
Definition
NAD+ from NADH and H+.
Term
the efficiency of glycolysis is approximately _____%.
Definition
2.
Term
anaerobic pathways provide enough energy to meet all of th energy needs of...
Definition
many unicellular and some multi-cellular organisms.
Term
aerobic respiration?
Definition
is the process of pyruvic acid breaking down and NADH is used to make larg amounts of ATP when oxygen is PRESENT.
Term
mitochondrial matrix?
Definition
the space inside the inner membrane of a mitochondrion.
Term
anaerobic respiration
Definition
the process of converting pyruvic acid into small amounts of ATP when oxygen is ABSENT.
Term
which reactions of the aerobic respiration occur in the inner mitochondrial membrane?
Definition
the pyruvic acid produced in glycolysis diffuses accros the double membrane of a mitochondrion and enters the mitochondrial matrix.
Term
the equation for the complete oxidation of glucose in aerobic respiration:
Definition
C6H12O6 + 6O2 -----> 6CO2 + 6H2O + ATP
Term
how is the structure of a mitochondrion well adapted for the activities it carries out?
Definition
the mitochondrion has a greater surface area. also, the mitochondrial matrix contains the enzymes needed to catalyze the reactions of the Krebs cycle.
Term
why are the fermentation pathways referred to as "anaerobic pathways?
Definition
because fermentation usually occurs in the ABSENCE of oxygen.
Term
what are the energy containing products of glycolysis?
Definition
2 ATP molecules.
