<span>Addition of an enzyme, for example amylase will increase the rate at which the starch is broken down into glucose. Amylase functions by rupturing the disaccharide bonds between glucose molecules releasing these into solution. If iodine had been added as an indicator of the presense of starch, the color will fade from brown to very light in a short time.</span>

g To answer this question, you may reference the Metabolic Map. Select the steps of glycolysis in which ATP is produced. phospho

Answer:

a) Total of ATP produced in glycolysis is equal to 2

ATP produced:

i) 1,3‑bisphosphoglycerate → 3‑phosphoglycerate (2 ATP are produced)

ii) phosphoenolpyruvate→pyruvate (2 ATP are produced)

b) 26 pyruvate molecules.

Explanation:

a) Glycolysis consists of two steps in which ATP is consumed and two steps in which ATP is released.

ATP produced = 4

ATP consumed = 2

The total of ATP produced in glycolysis is equal to 2 (4-2)

ATP produced:

i) 1,3‑bisphosphoglycerate → 3‑phosphoglycerate (2 ATP are produced)

ii) phosphoenolpyruvate → pyruvate (2 ATP are produced)

b) In the sixth step of glycolysis, inorganic phosphate molecules are consumed:

glyceraldehyde-3‑phosphate → 1,3‑bisphosphoglycerate

2 pi are added in glycolysis. As each glucose molecule undergoes glycolysis, the pi required by the 13 glocosa molecules is 26 (13 * 2). Glycolysis of each glucose produces 3 pyruvates, so 13 glucose molecules will produce 26 pyruvate molecules.

The energy needed to "pump" sodium outside the cell in active transport is _____.

Bezzdna [24]

The correct answer is ATP

This stands for Adenosine Triphosphate which is the main source of all energy in the body. It is used in all types of active energy usage and is produced with processes such as the krebs cycle.
