Exam 3: Cell Metabolism

Under anaerobic conditions, what is pyruvate converted to and where does this occur?

An increase in temperature increases the potential energy of molecules.

Describe the process whereby energy is obtained by glucose oxidation.

Gluconeogenesis refers to synthesis of and occurs in .

A single enzyme could be simultaneously affected by both allosteric regulation and covalent regulation.

Chemiosmotic coupling refers to

Which of the following contains glucose- 6- phosphatase?

In a metabolic pathway, the enzyme working the slowest in that pathway is known as the enzyme.

A reaction is at equilibrium when the rates of the forward and reverse reactions are equal.

The organ that stores glucose as glycogen and then provides glucose to the blood when needed is the

C6H12O6 + 6O2 -6CO2 + 6H2O is an example of what type of reaction?

What is the final acceptor of electrons in the electron transport?

Glucose is stored in the form of glycogen primarily within what two organs?

Complete oxidation of 1 mole glucose produces 6 moles of water and 6 moles of carbon dioxide.

A substrate is the same as a

Chemical reactions are only able to occur in one direction.

The addition of two hydrogens and two electrons to NAD+ is an example of what type of chemical reaction?

If the energy change of a reaction (OE)is positive, then

An enzyme that catalyzes phosphorylation of a protein is called a . An enzyme that catalyzes dephosphorylation of a protein is called a(n).

In this model of enzyme activity, both substrate and product can bind to the active site.
