Question

Explain nutrition and respiration in bread moulds (one point each)

Answer 1

Answer:

The mold spreads over the surface of the substrate, sending its hyphae inward to absorb the nutrients. Sugar and starch are favored by the mold, so while growing on bread, the mold takes up nutrition from the carbohydrate compounds of the bread.

Anaerobic and Aerobic Respiration In the bread-making process, it is the yeast that undergoes cellular respiration. Anaerobic respiration -- also known as fermentation -- helps produce beer and wine and happens without the presence of oxygen, while aerobic respiration requires oxygen to be present.
