Question 1

Fermentation

Answer 1

A catabolic process that makes a limited amount of ATP from glucose (or other organic molecules) without an electron transport chain and that produces a characteristic end product, such as ethyl alcohol or lactic acid.

Question 2

Glycolysis

Answer 2

A series of reactions that ultimately splits glucose into pyruvate. Glycolysis occurs in almost all living cells, serving as a starting point for fermentation or cellular respiration.

Question 3

Four stages of the physiological response curve:

Answer 3

Lag; period of time for reactions to begin.
Log; when reactions proceed at a maximum rate.
Stationary; the time where the rate of reaction plateaus, due to an accumulation of end products or lack of substrate or reagents.
Death; the quantity of the dependent variable that is produced is outnumbered by the quantity that is consumed or degraded.

Question 4

Linear rate of reaction

Answer 4

Measured against the log phase of the physiological response curve.
