Question

The process of splitting larger molecules into smaller ones is an aspect of metabolism called _____ The synthetic aspect of metabolism is referred to as _____ A chemical process during which a substance gains electrons is called _____ The pathway through which glucose is degraded to pyruvate is referred to as _____ The reactions of _____ take place within the cytosol of eukaryotic cells. Before pyruvate enters the citric acid cycle, it is decarboxylated, oxidized, combined with coenzyme A, forming acetyl CoA, carbon dioxide and _____ In the first step of the citric acid cycle, acetyl coA reacts with oxaloacetate to form _____ Carbon leave the _____ as molecules of carbon dioxide. Dehydrogenase enzymes remove hydrogens from fuel molecules and transfer them to primary acceptors such as _____ and _____ _____ are intermediate electron carriers in the mitochondrial electron transport chain. In the process of _____, electron transport and ATP synthesis are coupled by a proton gradient across the inner mitochondrial membrane. The diffusion of protons through the _____ complex results in ATP synthesis. One important part of the feedback inhibition of aerobic respiration is the inhibitory effect of ATP on phosphofructokinase, an enzyme required to _____ A net profit of only two ATPs can be produced anaerobically from the _____ of one molecule of glucose, compared with a maximum of 38 ATPs produced in _____ Organisms that can respire aerobically but switch to fermentation when oxygen is in short supply are called _____ When deprived of oxygen, yeast cells obtain energy by fermentation producing carbon dioxide, ATP and _____ During strenuous muscle activity, the pyruvate in muscle cells may accept hydrogen to become _____ The role of the reaction described in question 17 is to regenerate _____ required in glycolysis.
