What is the function of the enzyme succinate dehydrogenase?
Fatty acids and triglycerides are an important source of nutrition and a dense form
of stored energy. Digestion of fats yields more energy per gram than digestion of
carbohydrates.
Each turn on the B-oxidation spiral results in the formation of a new acetyl COA
molecule. This molecule can then be used to generate more energy in
A) fatty acid synthesis
B) ketolysis
C) glycolysis
D) tricarboxylic acid cycle
E) oxidative phosphorylation
The glycolysis pathway is shown. Place the enzymes used in each of the ten labeled steps of the pathway. Be sure to scroll
down completely until pyruvate is formed.
