Answer:
The correct answer is option D. The enzyme inhibitor fits into the enzyme's active site, which prevents the enzyme from catalyzing the reaction.
Explanation:
Enzyme inhibitors are the biochemical or chemical substance which hinders the role and function of the enzyme by binding to the active site of an enzyme.
These can be explained into two categories:
Irreversible inhibitors: They bound to the enzyme with the assistance of covalent bonds and alters the affinity of the enzyme towards the substrate by changing the state of the dynamic destinations.
Reversible inhibitors: Theses are the particles that bind to the enzyme's active site with the assistance of non-covalent bonds, for example, hydrogen bonds, hydrophobic bonds, and others.
Thus, the correct answer is : option D.

<span>C) DNA polymerase can join new nucleotides only to the 3' end of a growing strand. </span>
This model of red and orange lines represents the process of transcription.
The 5' labels refer to the end of the strand with a nitrogenous base. false
The 5' label at the end of the DNA strand refers to the phosphate group of the last nucleotide of the strand.
The model correctly shows an arrowhead on the 3' ends of the strands. false
The arrowhead on the 3' ends of the DNA is incorrectly put there. This is because arrowheads are only used to show the direction of the formation of RNA.
The 3' labels refer to the end of the strand with a phosphate group. false
The 3' labels refer to the end of the strand with a hydroxyl group of the last nucleotide of the strand.
Hydrogen bonds between the red and orange strands are not shown but are implied by the model. true
The newly formed RNA molecule is bound to the template DNA with hydrogen bonds. Normally, models describing the transcription process need to show the presence of the hydrogen bonds.
The red lines represent DNA. true
The red lines represent the unwinded double-stranded DNA.
The orange lines represent RNA. true
The orange lines represent the RNA molecule formed based on the template strand of nucleotides
The model shows the correct polarity between the orange and red strands. false
The RNA polymerase builds the RNA molecule by creating a strand that grows from 5' to 3' (this is correctly shown at the model). However, the template strand of DNA is read by the DNA polymerase in the 3' to 5' direction. Therefore, the model needs to show that the RNA molecule is bound to the other strand of DNA, the one with the 3'-5' direction.
