Include which molecules are being consumed. The metabolic process providing my energy while I was walking at an easy pace is aerobic metabolism. During aerobic metabolism‚ mitochondria absorb from the surrounding cytoplasm these molecules: ADP‚ phosphate ions‚ O2‚ and organic substances like pyruvate. These molecules go through the citric acid cycle. The electron transport chain is also involved to create ATP. For each molecule of pyruvate that goes into the citric acid cycle‚ the cell gains 17 ATP

In which some of them at low concentration are compulsory micronutrients‚ while the same at higher concentrations such as Cd‚ Hg‚ As are intensely toxic to the metabolic activities of the plants (Reeves and Baker‚ 2000; Fernandes and Henriques‚ 1991). Agricultural soil is contaminated by heavy metals‚ has become a critical environmental concern due to their potential

short-term‚ and long-term memory. • What is the role of glycolysis? Include the reactants and the products. Where does it occur? They are used to raise the energy content of the reactants in the first and third steps of glycolysis (glucose-6-phosphate and fructose-1‚6-diphosphate). Chemical reactions proceed more "easily" when they go from a high-energy state to a lower-energy state. Another way of saying it that they become "more reactive‚" since the ATPs are supplying the activation energy

dehydration of the carbohydrate by concentrated sulfuric acid to produce an aldehyde which condenses with two molecules of phenol‚ resulting in a coloured compound. Molisch reagent is a solution of α-napthol in 95% ethanol. The aldehydes produced are pentoses and hexoses which can derive to furfural and hydroxymethyl furfural respectively. The Molisch reagent further reacts with furfural to yield a coloured product which is a deep violet ring at the interface of two layers. The reaction occur at the junction

cycle and the Electron Transport Chain and chemiosmosis. Recall that at the end of glycolysis there is a net production of two molecules of ATP and two molecules of NADH. The ATP is produced via substrate-level phosphorylation; in this reaction‚ a phosphate group on an organic molecule is transferred directly (along with high-energy electrons) onto a molecule of ADP. Substrate-level phosphorylation also occurs once during the Krebs cycle.For those organisms that completely oxidize glucose‚ the end product

Question Give an account of how enzymes work with particular reference to factors that affect their activities. Answer All living things require catalysts to catalyse the reaction which they carry out to survive. Enzymes are the catalysts of biological systems without enzymes reactions in cells would occur all much to slow a rate and the organism would not survive. Most enzymes‚ with the exception of some RNA catalysts‚ are proteins. They often require a co factor such as zinc or iron‚ or a complete organic
