Glycolysis And Fermentation

Question 1

Step one of Glycolysis

Answer 1

2 phosphate groups from two ATP attach to one molecule of glucose, forming a six carbon compound.

Question 2

Step 2 of Glycolysis

Answer 2

Six carbon compound then splits into 2, 3 carbon molecules called G3P.

Question 3

Step Three of Glycolysis

Answer 3

The two G3P molecules are oxidized and each receives two phosphate. 2 NAD+ is reduced to NADH

Question 4

Step 4 of Glycolysis

Answer 4

The 2 G3P oxidizes and loses their phosphate while ADP reduces to ATP. 2 molecules of pyruvate is created.

Question 5

Lactic Acid Fermentation

Answer 5

An enzyme converts of pyruvic acid made during glycolysis into another three carbon molecule, lactic acid. Transfer one H+ from NADPH and another H+ to pyruvic acid. The NAD+ created is used in glycolysis.

Question 6

Alcoholic Fermentation

Answer 6

Convert pyruvic acid into ethyl alcohol. After glycolysis, A CO2 is removed from pyruvic acid leaving a two carbon compound. Two hydrogen are added to the 2 carbon compound to form ethyl alcohol.

Question 7

Glycolysis

Answer 7

Biochemical pathway in which one six carbon molecule of glucose is oxidized to produce two three carbon molecules of pyruvic acid.
