Summary Introduction

To name:

The pathways diagrammed in parts (a), (b), and (c) of the given figure.

Introduction:

Cellular mechanisms involved in many reactions in which the transfer of electrons from one molecule to another take place by means of oxidation-reduction reactions. The oxidation and reduction reactions are always coupled, the form of undergoes oxidation and another form undergoes reduction simultaneously.

Summary Introduction

To review:

The anabolic and catabolic mechanisms in the given pathways.

Introduction:

The cellular mechanism of all living organisms requires the energy for its metabolism. However, the conversion of energy from the organic compounds undergoes the catabolic and anabolic process in different pathways, such as glycolysis, TCA and Calvin-Benson cycle to produce the energy in the form of ATP.

Explanation of Solution

  1. Glycolysis and the Citric acid cycle are the major pathways for anabolic and catabolic mechanisms of all organic molecules, such as carbohydrates, lipids, and proteins. Glycerol is catabolized as Dihydroxyacetone phosphate in the Glycolysis pathway (a) and fatty acids are catabolized as acetyl CoA int he TCA cycle (b).

  2. Glutamic acid is catabolized in the Krebs cycle (c). Glutamic acid is an amino acid which is catabolized by Kreb’s cycle at α-ketoglutaric acid which is formed from isocitric acid.

  3. In the Calvin-Benson cycle, Glyceraldehyde 3-phosphate is the end product, which enters into glycolysis. In glycolysis, the glucose is oxidized into pyruvate which is decarboxylated to acetyl group and entered into the Kreb’s cycle.

  4. The Calvin cycle requires 18 molecules of ATP between glucose and glyceraldehyde 3- phosphate.

  5. Three molecules of carbon dioxide (CO2) is released in the Kreb’s cycle,

    • Between pyruvate to acetyl CoA.
    • Between isocitric acid to α-ketoglutarate (TCA cycle).
    • Between α-ketoglutarate to succinyl CoA.
  6. The long chain hydrocarbon like such as acetyl group is catabolized in the TCA cycle at acetyl CoA. This acetyl group like hydrocarbons are catabolized by beta-oxidation which enters into the Kreb’s cycle.

  7. The production of NADH, FADH2 or NADH in glycolysis, Calvin-Benson and TCA cycles are,

  8.  UtilizesProduces
    Glycolysis 2 NADH
    Calvin-Benson cycle6 NADPH 
    Pyruvate to acetyl CoA 1 NADH
    Isocitrate to α-ketoglutaric acid 1 NADH
    α-keto-glutaric to succinyl CoA 1 NADH
    Succinate to fumarate 1 FADH2
    Malate to oxalate 1 NADH
  9. The anabolic and catabolic pathways are integrated between,

    • In glycolysis, the anabolic and catabolic pathways integrated into dihydroxyacetone phosphate.
    • In the TCA cycle, the anabolic and catabolic pathways integrated into acetyl, oxaloacetic acid and ketoglutaric acid.

Below is a list of steps that occur after an exercising muscle cell begins degrading amino acids for ATP production. For each step, choose (A) if the process occurs in the muscle cell and (B) if the process occurs in the liver. It will be easiest to answer this question if you first put the steps in order, then decide in which organ they occur. ______ Alanine is transaminated with a-ketoglutarate.______ Branched chain amino acids are transaminated with a-ketoglutarate.______ Glutamate is deaminated.______ Glutamate is transaminated with pyruvate.______ Ketoacid skeletons resulting from branch chain amino acids enter the CAC.______ Pyruvate enters gluconeogenesis.______ Urea is formed from the nitrogen removed from the original branched chain amino acid.
