21 DECEMBER 2021 CURRENT AFFAIRS QUIZ

removes water from a double bond

uses NADH to change the oxidation state of the substrate

uses ATP to add a phosphate group to the substrate

removes phosphate groups of substrates

α-1,4 and α-1,6 linkages

α-1,4 and β-1,6 linkage

α-1,4 linkage

α-1,6 linkages

High levels of ATP keep the pathway going in a forward direction

The enzymes of glycolysis only function in one direction

There are essentially three irreversible reactions that act as the driving force for the pathway

Glycolysis occurs in either direction

Phosphofructokinase

pyruvate kinase

glyceraldehyde-3 -dehydrogenase

phosphoglycerate kinase

is lost as heat

remains in the products of metabolism

is stored as fat.

is used to reduce NADP

The pathway requires two moles of ATP to get started catabo-lizing each mole of glucose

The pathway does not require oxygen

The pathway oxidizes two moles of NADH to NAD+ for each mole of glucose that enters

ADP is phosphorylated to ATP via substrate level phosphorylation

Nucleotides

Polysaccharides

Proteins

Amino acids

both (a) and (b)

the muscles by phosphorolysis

the muscles by hydrolysis

the liver by phosphorolysis

only in yeast

only in eukaryotes

primarily in animals excluding particles

in all living organisms

both (b) and (c)

the gibbs free energy will be positive

the gibbs free energy will be negative

more products will be formed
