ADP is a
(b)
Interpretation: To indicate whether the biochemical function of
Concept introduction: The sum of various chemical reactions occurring in the human body is called metabolism and the reactions individually are known as metabolic reactions. During these metabolic reactions, the various metabolic intermediates are formed for the short time to complete the reactions.

Concept introduction: The sum of various chemical reactions occurring in the human body is called metabolism and the reactions individually are known as metabolic reactions. During these metabolic reactions, the various metabolic intermediates are formed for the short time to complete the reactions.
Flavin adenine dinucleotide exists in two forms: oxidized form
(d)
Interpretation: To indicate whether the biochemical function of Coenzyme A molecule involves transfer of (1) phosphate groups, (2) electrons, or (3) acetyl groups.
Concept introduction: The sum of various chemical reactions occurring in the human body is called metabolism and the reactions individually are known as metabolic reactions. During these metabolic reactions, the various metabolic intermediates are formed for the short time to complete the reactions. Coenzyme A is an example of a metabolic intermediate.
Coenzyme A (CoA) is a coenzyme which is utilized in various metabolic reactions. The functions of coenzyme A include oxidation of pyruvate in the citric cycle and fatty acid oxidation.

- " is The structure of the bicarbonate (hydrogen carbonate) ion, HCO3-, HCO3 best described as a hybrid of several contributing resonance forms, two of which are shown here. HO :0: :Ö: HO + Bicarbonate is crucial for the control of body pH (for example, blood pH: 7.4). A more self-indulgent use is in baking soda, where it serves as a source of CO2 CO₂ 2 gas, which gives bread and pastry their fluffy constituency. (i) Draw at least one additional resonance form. = (ii) Using curved "electron-pushing" arrows, show how these Lewis structures may be interconverted by movement of electron pairs. (iii) Determine which form or forms will be the major contributor(s) to the real structure of bicarbonate, explaining your answer on the basis of the criteria in Section 1-5.arrow_forwardWhich of these is the best use of a volumetric flask? measuring how much liquid it contains delivering a precise amount of liquid to another container holding solutions making solutions of precise concentrationarrow_forwardYou're competing on a Great British television game show, and you need to bake a cake.
