(a)[5]
Complete the sentences about aerobic and anaerobic respiration. Anaerobic respiration differs from aerobic respiration because [BLANK] is not required to break down glucose molecules. The amount of [BLANK] released from each glucose molecule is much lower in anaerobic respiration. In humans, anaerobic respiration occurs in [BLANK] cells during strenuous exercise. It produces [BLANK] from glucose. Another type of anaerobic respiration occurs in yeast cells. In this case, glucose is broken down into alcohol and [BLANK].
(b)[2]
State two ways in which the products of anaerobic respiration in yeast may be used by humans.
(c)[2]
Describe the pattern shown in Fig. 2.1. Support your answer with data.
