Concept Introduction:
Aerobic: The system that moves your blood through your lunges, where it is loaded with oxygen and then distributes it to every part of your body.
Anaerobic: It is a threshold is the exertion level between aerobic and anaerobic training. The AT is the point during exercise when your body must switch from aerobic to anaerobic
(b)
Interpretation Introduction
Interpretation:
Which enzyme involved in pyruvate into acetyl co-enzyme has to be given.
Concept Introduction:
Citric acid cycle
- This is a series of enzyme-catalysed
chemical reactions , which is of central importance in all living cells that use oxygen as part ofcellular respiration . - This cycle initially with the transfer of a two-carbon acetyl group from acetyl-CoA (co-enzyme) to the four-carbon acceptor compound (oxaloacetate) to from a sis-carbon compound like citrate.
- The citrate than goes through a series of chemical transformation, losing two carbonyl groups as the carbon dioxide.

The complete oxidation of palmitoyl-CoA to carbon dioxide and water is presented by the overall equation:
Palmitoyl-CoA + 23O2 + 108Pi + 108 ATP + 23H2O → CoA + 16 CO2 + 108 ATP + 23H2O
Water is also produced in the reaction
ADP + Pi → ATP + H2O
But not included as a product in the overall equation. Why?
For each of the central pathway intermediates given below, calculate how many ATP equivalents can be generated by complete oxidation of the compound to CO2:
1. Acetyl-CoA
2. Pyruvate
3. GAP (glyceraldehyde-3-phosphate)
And please explain why.

(a) Stearic acid (b) Oleic acid (c) Palmitic acid (d) Linoleic acidarrow_forwardIn 1937, two German biochemists published a paper proposing these reactions as part of glucose oxidation: citrate → isocitrate → α-ketoglutarate →succinate → fumarate → malate → oxaloacetate. Adding succinate, fumarate, or malate to thin slices of tissue increased oxygen consumption, supporting the hypothesis that these molecules are intermediates in the process. However, they were puzzled by the observation that these intermediates were still present in the reaction mixture at the end of the experiment. They had thought that intermediates would be consumed as they were converted to the next molecule in the pathway. What explains the observation that these intermediates were still present? a) The pathway is a cycle, constantly regenerating intermediates as glucose is broken down. b) Succinate, fumarate, and malate are not reactants but catalysts, and catalysts are not consumed in the process. c) Succinate, fumarate, and malate increase metabolism and therefore oxygen consumption,…arrow_forwardD) Carbohydrate catabolism involves substrate-level phosphorylation. E) My answer is not here 27. The adduct acetoacetyl-acyl carrier protein is formed as an intermediate during fatty acid biosynthesis. The CO2 used to synthesize malonyl-S-CoA is lost. Would this help make the reaction more or less energetically favorable? A) Loss of CO2 increases entropy (AS) and therefore decreases the favorability of the reaction (AG). B) Loss of CO2 has no effect on entropy (AS) and therefore does not affect the favorability of the reaction (AG). C) Loss of CO2 increases entropy (AS) and therefore increases the favorability of the reaction (AG). D) Loss of CO2 decreases entropy (AS) and therefore decreases the favorability of the reaction (AG). E) Loss of CO2 decreases entropy (AS) and therefore increases the favorability of the reaction (AG).arrow_forward
