Term
the process by which cells create ATP from organic compounds
Definition
Cellular respiration
Term
when glucose is oxidized into 2 molecules f pyruvic acid [this is a biochemical pathway]
Definition
Glycolysis
Term
cells use this to continue glycolysis without the usage of oxygen
Definition
Lactic Acid Fermentation
Term
cells use this to convert pyruvic acid into ethanol without the usage of oxygen
Definition
Alcoholic Fermentation
Term
Where does glycolysis take place?
a. in the cytosol
b. in the mitcochondria
c. only is oxygen is absent
d. only is oxygen is absent
Definition
answer:
a.
Term
What is the net yield of ATP in glycolysis?
Is it aerobic or anaerobic?
Definition
2
anaerobic
Term
During glycolysis, glucose is
a. produced from 2 pyruvic acid molecules
b. converted into 2 molecules of ATP
c. partially broken down and some of its stored energy is released
d. partially broken down and its stored energy is increased
Definition
c
Term
Which isn't an energy containing product of glycolysis?
a. ATP
b. lactic acid
c. pyruvic acid
d. NADH
Definition
b
Term
What does anaerobic mean? aerobic
Definition
works without oxygen; works with oxygen
Term
the area within the mitochondrial membrane
Definition
the mitochondrial matrix
Term
a biochemical pathway that produces ATP, hydrogen and carbon dioxide using coenzyme A
Definition
The Krebs cycle
Term
during redox reductions, this molecule accepts electrons
Definition
FAD
Term
the breakdown product of glucose that diffuses into the mitochondrial matrix for further breakdown is
a. acetyl CoA
b. pyruvic acid
c. oxaloacetic acid
d. citric acid
Definition
b
Term
the krebs cycle
a. produces 2 molecules of carbon dioxide
b. produces a six carbon molecule from six molecules of carbon dioxide
c. produced NAD+ from NADH and H+
d. generates most of the ATP produced in aerobic respiration
Definition
a
Term
the electron transport chain of aerobic respiration
a. generates atmospheric oxygen [o2] from water
b. produces NADH by chemiosmosis
c. pumps electrons into the mitochondrial matrix
d. pumps protons into the space between the inner and outer mitochondrial membranes
Definition
d
Term
In the krebs cycle, what molecules acquire the most of the energy that is released by oxidation of acetyl CoA? How many of these molecules are produced during each turn of the cycle?
Definition
NADH, 3 molecules
Term
which reactions of aerobic respiration occur in the inner mitochondrial membrane?
Definition
the electron transport chain reacrtions
Term
Glycolysis?
1. Net yield ATP
2. Where does it occur?
3. Aerobic or anaerobic?
Definition
1. 2
2. cytosol
3. anaerobic
Term
Krebs Cycle
1. Net yield ATP
2. Where does it occur?
3. Aerobic or anaerobic?
Definition
1. 2 ATP
2. Mitochondria
3. Aerobic
Term
Electron transport chain
1. Net yield ATP
2. Where does it occur?
3. Aerobic or anaerobic?
Definition
1. 34
2. mitochondria
3. aerobic
Term
T/F
Fermentation produces ATP
Definition
F
Term
What is this?
1. 2 ATP molecules transfer phosphate to a glucose molecule
2. 6-carbon compound is broken down to the 3-carbon compound, PGAL, each with a phosphate group
3. 2 NADH molecules are produced. One phosphate each is transferred to each 3-carbon compound [PGAL]
4. phosphate groups are removed each to create ATP. Each 3-carbon compound is converted to a 3-carbon pyruvic acid, producing 4 ATP molecules [net yield 2]
Definition
Glycolysis
Term
What is this?:
Regenerates NAD+ which can later be make to make more ATP
Definition
Fermentation
