Cellular Respiration Overview & Glycolysis

Fats, proteins, and carbohydrates are reservoirs of energy that, through a series of chemical reactions, become available to the cells. What is this overall series of reactions called?

True or False: Respiration always requires oxygen to occur.

In eukaryotic cells, all the respiratory steps except for glycolysis occur within the:

Glycolysis occurs in the:

The series of controlled chemical reaction steps that break down glucose into pyruvate is called 1($), a term that literally refers to the lysis, or splitting, of glucose.

Based on the diagram, how many 3-carbon pyruvate molecules are ultimately produced from one molecule of glucose during glycolysis?

Which molecule provides the activation energy needed to initiate the breakdown of glucose molecules?

True or False: Enzymes increase the amount of activation energy required to start a chemical reaction.

Chemically, 1($) is defined as the loss of an electron, usually taking place through the addition of oxygen or the subtraction of hydrogen.

Most human enzymes function best at which approximate temperature?

Why does the cell break down glucose through many small, controlled steps rather than releasing all the energy at once?
