The TCA cycle occurs in mitochondria.

Each pair of hydrogens generated in glycolysis are used to

Metabolism is a term that refers to all of the reactions in the body that involve energy transformations.

________ muscle is better adapted to anaerobic conditions than cardiac muscle.

The Cori cycle involves formation of glucose made by gluconeogenesis in the liver from lactic acid produced by fermentation in skeletal muscles.

Which of the following cells relies solely on anaerobic metabolism of glucose?

Glycolysis results in a net gain of two ATP formed by direct _____________ of ADP molecules using phosphates taken from glycolytic intermediates.

What is the inadequate supply of blood to an organ called?

What is the purpose of white fat?

In glycolysis,glucose is converted to glycogen.

The majority of energy within the body is stored as triglycerides.

Skeletal muscle contains glucose 6-phosphatase to produce free glucose from glucose 6-phosphate.

Which of the following is NOT a main substrate for gluconeogenesis?

Oxygen is reduced by the action of the electron transport chain.

The electron transport chain system functions to create a proton gradient across the outer mitochondrial membrane.

The process of fat formation from acetyl CoA is called

Glycolysis converts glucose into two ______________ molecules.

Acetyl CoA is

What structures allow H⁺ to diffuse back across the inner mitochondrial membrane to the matrix?

In the complete process of aerobic respiration,the major source of reduced NAD and FAD is glycolysis.
