Cellular Energetics 1
What is glycolysis?
The major energy source for some tissues, especially the adult heart muscle.
What are fatty acids?
Generates high-energy electrons.
What is the citric acid cycle?
The source of the high-energy electrons NADH and FADH2.
What is the citric acid cycle?
The effect that proton pumping has on the pH of the mitochondrial matrix.
What is raise the pH?
The biological breakdown of complex substances into simpler ones.
What is catabolism?
Product formed during aerobic metabolism.
What is CO2 and H2O?
More efficient than carbohydrates for storage of energy.
What are triglycerides?
The mechanism that produces about 28 ATPs.
What is oxidative phosphorylation?
Occurs if the mitochondrial membrane potential is lost.
What is cell death?
Coenzyme A linked to acetic acid group.
What is a link reaction?
Location where anaerobic metabolism takes place.
What is the cytoplasm?
Small-molecule electron carrier in the electron transport chain that carries both protons and electrons.
What is coenzyme Q/ubiquinone?
Inhibitor of pyruvate kinase.
What is ATP?
Location where electron transport chain takes place.
What is the mitochondrial membrane potential?
The rate limiting step for glycolysis.
What is phosphofructoskinase-1?
The product formed during aerobic metabolism in animals.
What is lactic acid?
Enzyme responsible for converting ADP to ATP.
What is ATP synthase?
Inhibitor for hexokinase.
What is glucose-6-phosphate?
Activator of phosphofructokinase-1.
What is AMP?
Location where aerobic metabolism takes place.
What are the cytoplasm and mitochondria?
The product formed during aerobic metabolism in yeast.
What is ethanol and CO2?
Site where citric acid cycle takes place.
What is the mitochondrial membrane?
Has a very high mutation rate due to not having sufficient repair systems or protective histones.
What is mitochondrial genome?
Inhibitor of phosphofructokinase-1.
