Which of the following substances derived from lipid catabolism serves as a precursor for glucose synthesis: acetoacetyl CoA acetone palmitate acetate O glycerol

Lactose is found in milk products. It is converted by the body into a usable form in a series of chemical reactions. The diagram shows the series of reactions that convert lactose into a usable form. Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4 galactose- 1-phosphate Lactose galactose glucose- 1-phosphate glucose- 6-phosphate If enzyme 2 is denatured (destroyed), the levels of which substance will increase?

Which of the following enzymes is responsible for breaking a1-4 glucose bonds and forming a1-6 glucose bonds? glycogen phosphorylase branching enzyme glycogen synthase debranching enzyme

For each of the following sentences, fill in the blanks with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase should be used only once. amino acids                galactose            nucleotides carbon fixation            glucose              oxidative phosphorylation citric acid cycle           glycogen            pyruvate fatty acid                   insulin               starch fermentation               lactate               triacylglycerol       A carbon atom in a CO2 molecule in the atmosphere eventually becomes a part of one of the enzymes that catalyzes glycolysis in one of your cells. The CO2 first enters a cell in a corn leaf, where photosynthesis fixes the carbon to make it part of a sugar molecule; this travels from the leaf to an ear of corn, where it is stored as part of a polysaccharide            molecule in the corn seed. You then eat a corn chip made from the corn seed. You digest the corn seed, and the…

The amount of ATP that glycerol can produce is less than 50% one glucose unit 50% of one glucose unit a little above 50% of one glucose unit. 90% more than one glucose unit

Which of the following biochemical reactions should be classified as endergonic (endothermic)?  conversion of glucose into amylopectin conversion of lactose into glucose and galactose conversion of glycogen into glucose conversion of sucrose into glucose and fructose conversion of amylose into glucose

Compare the amount of ATP formed during the metabolization of glucose, proteins and a fatty acid (C16H32O16) by means of a table.

Lifting 5 Kg consumes 110 moles ATP. Which of the following metabolites, when oxidized in muscle cells will provide this energy? 17:0 fatty acid 16:0 fatty acid 18:1 fatty acid trisaccharide glycogen 50 glucose units (anaerobic) -

Glycolysis occurs in two stages. Describe what is accomplished in each stage.
