How does food concentration affect yeast activity

Biology
1 answer:
jarptica [38.1K]3 years ago
5 0

Yeast food is sugar and its concentration affect yeast’s growth and activity. The process by which yeast metabolize sugar is called fermentation. A sugar concentration that is not very high (up to 3%), increase the fermentation rate. But, with over 3% sugar, the fermentation rate no longer increases. Above 6%, sugar actually decreases the rate  because it begins to dehydrate the yeast cells. This effect is called crenation.

Answer:

The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color. Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose then releases the unused components such as oxygen.

What is true about the function of the electron transport system (ETS)?
FrozenT [24]

The correct answer is the last option.

The first option does not make sense as the electron transport chain makes the most ATP from the whole ATP synthesis cycle including glycolysis and the Kreb's Cycle. It also does not make NADH, but instead splits NADH into NAD- and H+. The H+ are used later to make ATP.

The second option also does not make sense as a "lysosome" is a digestive "pocket" in the cell, used for taking in and digesting food for the cell.

The third option also does not make sense as it does not produce NADH and is not during glycolysis. The electron transfer chain breaks up NADH and FADH2 and is the last step in the ATP synthesis process, after glycolysis and Kreb's Cycle.

The last option is correct. The electron transfer chain has the ability to make 34 molecules of ATP (in theory; so in real-life this does not always happen). The electron transfer chain does break down several compounds derived from glucose in a series of chemical reactions that do occur in the cristae of the mitochondrion.
