Concept explainers
Interpretation:
To identify the process that encountered the intermediate
Concept introduction:
Glucose is a monosaccharide with the molecular formula
Glycogenesis is the
An intermediate is defined as the transient species that is formed from the reactants in the preceding step and gets consumed in the subsequent steps to generate the products. An intermediate is formed within a multi-step reaction mechanism.

- What are the typical fates for fatty acids in the liver (select all that apply)? O They are oxidized and converted into ketone bodies. O They are oxidized to yield acetyl-CoA and NADPH. O They are used to synthesize triacylglycerol. O They are oxidized and converted into glucose. O They are oxidized and used in the synthesis of cholesterol.arrow_forwardQuestion.

Number them in Acetyl CoA using the original number from glucose. b) Are any carbons from acetyl CoA removed as CO2 during the first "turn" of the citric acid cycle? c) What glucose carbon(s) is (are) the first to be removed as CO2 in the citric acid cycle?arrow_forward15.7) Determine whether each of the following changes is an oxidation or reduction. a) gain of electrons reduction b) loss of electrons oxidation c) Fe²+ to Fe³+ oxidation d) NADH to NAD+ oxidation lost bond to hydrogen atom e) FAD to FADH₂ reduction gained bond to hydrogen atom f) CH4 to CO₂ oxidation gained bonds to oxygen atoms and lost bonds to hydrogen atoms g) NAD+ to NADH reduction gained bond to hydrogen atom EXPLANATION: A useful mnemonic to differentiate oxidation and reduction is the term "OILRIG" (Oxidation is the Loss of electrons; Reduction is the Gain of electrons). It is possible to identify redox reactions for inorganic compounds by inspecting the chemical equation and determining if electrons are transferred from one species to another. If the charge of an atom or ion in a reactant was increased (toward positive) in the conversion of reactants to products, an oxidation occurred. If the charge of an atom or ion in a reactant was decreased (toward negative) in the…arrow_forward
