If phosphofructokinase experienced a mutation that interfered with substrate binding, then what other enzyme is going to be most immediately impacted in terms of accessing substrate? A. aldolase
B. fumarase
C. glucolactonase
D. hexokinase

A. aldolase

Explanation:

Phosphofructokinase, is an enzyme which is vital in the regulation of fermentation. It is involved in the glycolysis process.

When it experiences a mutation that was being interfered with the substrate binding, we should note that the enzyme that is going to be most immediately impacted in terms of accessing substrate is aldolase.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

(b) which contains higher levels of vitamin b, oranges or spinach?

you can eliminate a, c, and d because they are questions based on opinions.
