Answer:

A. Enzymes lower the activation energy of reactions

Explanation:

Enzymes are biochemical catalyst produced in the body that alter the rate of digestion of food substance.

Like other chemical catalyst, enzymes reduce the activation energy (which is the energy the reactants must attain before being converted to products) in a chemical reaction.

As such, Enzymes lower the activation energy of reactions

If acetyl-CoA is labeled with 14C at its methyl group, how many rounds of the cycle are required before 14CO2 is released?
Elis [28]

Answer:

14 CO₂ will be released in the second turn of the cycle

Explanation:

<u>Complete question goes like this</u>, "<em>The CO2 produced in one round of the citric acid cycle does not originate in the acetyl carbons that entered that round. If acetyl-CoA is labeled with 14C at the carbonyl carbon, how many rounds of the cycle are required before 14CO2 is released?</em>"

<u>The answer to this is</u>;

  • The labeled Acetyl of Acetyl-CoA becomes the terminal carbon (C4) of succinyl-CoA (which becomes succinate that is a symmetrical four carbon diprotic dicarboxylic acid from alpha-ketoglutarate).
  • Succinate converts into fumarate. Fumarate converts into malate, and malate converts into oxaloacetate. Because succinate is symmetrical, the oxaloacetate can have the label at C1 or C4.
  • When these condense with acetyl-CoA to begin the second round of the cycle, both of these carbons are discharged as CO2 during the isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase reactions (formation of alpha-ketoglutarate and succinyl-CoA respectively).

Hence, 14 CO₂ will be released in the second turn of the cycle.

ASHA 777 [7]

Answer:

Its a substitution mutation because one of the specific base, G is replaced by A.

This is a Point Mutation because Point mutation brings changes in the structure of a gene because of the substitutions with another base pair. Like in this case, G is substituted by A. In case of frameshift mutations, there is a change in the number of nucleotides due to either insertions or deletions of the nucleotides, which is not in this case.
