During which process is ethanol produced?
Kipish [7]

Answer:

Alcohol fermentation

Explanation:

When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration

One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.

Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture

This process is taken advantage of to brew beer and wine.

Triss [41]

Answer:

CO2 is supplied by mammals and other living animals exhaling, producing CO2 this is absorbed through their leaves, and stems

H2O is supplied by the water cycle, nearby rivers, oceans, creeks etc. This is soaked up through their roots. Excess sugars are also stored in the roots as food.

Sunlight is provided in the atmosphere and the chlorophyll absorbs this.
