2.
During catabolism, only about 40% of the energy available from oxidizing glucose is used to synthesize ATP. Remaining 60%
is lost as heat
is used to reduce NADP
remains in the products of metabolism
is stored as fat.
Answer: Option

3.
Why does the glycolytic pathway continue in the direction of glucose catabolism?
There are essentially three irreversible reactions that act as the driving force for the pathway
High levels of ATP keep the pathway going in a forward direction
The enzymes of glycolysis only function in one direction
Glycolysis occurs in either direction

4.
The released energy obtained by oxidation of glucose is stored as
a concentration gradient across a membrane
ADP
ATP
NAD+

5.
A kinase is an enzyme that
removes phosphate groups of substrates
uses ATP to add a phosphate group to the substrate
uses NADH to change the oxidation state of the substrate
removes water from a double bond
