Question

HEEEEELLLLP PLEEASEE
I could really use some help right now please. How does cellular respiration occur? Or more specifically, how is glucose converted into ATP?

Answer 1

Tried Youtube?

Answer 2

yup :/

Answer 3

Cellular respiration is the process that releases energy by breaking down food molecules in the presence of oxygen. Cellular repiration takes place in the mitochodrion. The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes place in the cytoplasm. The Krebs cycle and electron transport takes place in the mitochondria. Aerobic respiration (requires oxygen) includes glycolysis, krebs cycle, and electron transort with end products of carbon and hydrogen and a net gain of 36 ATP. Aerobic respiration (does not require oxygen) includes fermentation including glycolysis with end products of lactic acid or ethyl alcohol and carbon; and a net gain of 2 ATP.

GLYCOLYSIS- is the process in which 1 molecule of glucose is broken in half, producing 2 molecules of pyruvic acid
-2 pyruvic acid are produced
-net gain of 2 ATP molecules
-NAD+ is reduced to NADH
-reaction:C6 H12 O6 + 2 ATP = 2 pyruvic acids + 4 ATP

Answer 4

Thank you :) but why is there a net gain of 2 ATP molecules?

Answer 5

The calculated net amount of ATP produced from one glucose molecule during fermentation is 2

Answer 6

straight from the test I just took.
