Biology

Question 1

Process of the Light Independent reaction

Question 2

Process of Glycolysis

Answer 2

1. Hydrolysis of 2ATP provides inorganic phosphates for the phosphorylation of glucose into glucose phosphate
   2.Lysis of Glucose Phosphate produces 2 molecules of Triose Phosphate (TP)
2. Oxidation of TP provides hydrogen ions to reduce NAD into NADH
   4.Dephosphorylation of TP provides inorganic phosphates for the phosphorylation of 4ADP to 4ATP
3. 2xPyruvate, 2xNADH, 2xATP

Question 3

Process of the Link reaction

Answer 3

1. 1 Co2 and 1 Hydrogen ions is removed from pyruvate forming acetate
2. Hydrogen ion is acceten by NAD to form reduced NAD
3. Acetate combines with coenzyme A to produce Acetyl Coenzyme A
4. 1x Acetyl-CoA, 1xNADH, 1xCO2

Question 4

Process of the Krebs Cycle

Answer 4

1. 2C molecule Acetyl Coenzyme combines with 4C molecule to form a 6C molecule
2. Oxidation of 6C molecule reduces 3NAD to 3NADH and 1FAD to 1FADH
   3.Removal of 2 CO2 from 6C molecule reforms 4C molecule which can combine with another acetyl CoA
3. 1 ATP is produced via substrate level phosphorylation

Question 5
