During anaerobic exercise, the process of lactate formation in the muscle,
Does not form CO2
Replenishes NAD+ for use in glycolysis
All of these
Converts Pyruvate to Lactate
Glycolysis is localized in what part of the cell?
Cytosol
Mitochondria
Endoplasmic reticulum
Ribosomes
In the process of glycolysis, glucose is converted to
Pyruvate
Oxaloacetate
Lactose
Ethanol
In step 7 of glycolysis, ATP is generated when a phosphate group is transferred directly from 1,3-diphosphoglycerate to ADP in a process known as
Oxidation
Substrate level phosphorylation
Oxidative phosphorylation
Transamination
NAD+ (nicotinamide adenine dinucleotide) is the hydrogen acceptor when
A reduction produces a C=O bond
An oxidation produces a C=C bond
An oxidation removes hydrogen to produce a C=O bond
A reduction produces a C-C bond
The coenzyme primarily involved in activating two carbon units (acetyl groups) is
ATP
Coenzyme A
FAD
NAD+
The Cori Cycle
Utilizes glyconeogenesis in the liver
Uses bloodstream to transport glucose from liver to muscle
All of these
Uses bloodstream to transport lactate from muscles to liver
The final products of catabolic reactions are:
lipids, oxygen and water
RNA and DNA
Glucose, lipids and glycogen
Carbon dioxide, water and ammonia
The portion of Coenzyme A that reacts with potential substrates is
An alcohol group
an acid group
a thiol group
A C=O group
The primary energy source for the brain is
Lactate
Glucose
Amino acids
Fructose
When glucose is oxidized to two pyruvate molecules, the net number of ATP molecules produced by direct phosphate transfer is
8
2
6
4
Under aerobic conditions, pyruvate produced in glycolysis can be converted to
Acetyl coenzyme A
glyceraldehyde-3-phosphate.
lactic acid
fructose-6-phosphate
Which of the following is true for the glycolytic pathway?
All reactions require ATP
All reactions are catalyzed by specific enzymes
NO ATP is produced
All reactions involve trioses
