Using site-directed mutagenesis, you have created a mutant form of chymotrypsin that has alanine substituted for the usual serin

e at position 195. Which of the following effects would your expect to observe? a. No effect or slight increase in affinity for substrate coupled to a complete loss of enzyme activity. b. A decrease in the affinity for substrate coupled to a decrease in enzyme activity. c. An increase in the rate of peptide-bond cleavage due to an increase in the rate of acid-base catalysis. d. An increase in the rate of peptide-bond cleavage due to an increase in the rate of covalent catalysis. e. A complete loss of enzyme activity due to the inability to bind substrate

Answer:

The correct answer is - option E.

Explanation:

Serine may not be affected by the mutation as it has no part of the hydrophobic binding site so it won't affect the affinity of the binding of the substrate. The peptide bond-breaking would not occur without the catalytic end or part so the enzyme would be the complete loss of enzyme activity due to site-directed mutagenesis that is created from the chymotrypsin.

Thus, the correct answer is - option E.

blondinia [14]

Answer:

Both electron transport and a proton gradient

Explanation:

The process of oxidative phosphorylation in mitochondria and electron transport chain in photosynthesis undergo chemiosmosis to produce ATP molecules.

Chemiosmosis is a process where the energy utilized by the movement of proton and electrons produces ATP molecules.

Both the processes involve the movement of electrons through electron carriers where the reduced energy is utilized to drive the flow of protons through the plasma membrane. This creates a proton gradient across the plasma membrane which rotates the ATP synthase and converts the ADP molecules into ATP molecules.

Thus, the selected option is correct.

Alexus [3.1K]
<h2>Answer </h2>
  • Hybridization
  • Recombinant DNA
  • Selective Breeding

<u>Explanation</u>

1. Cross-breeding; a method that unionizes gametes of differing genes to create a new individual is hybridization. It is the idea of combining atomic orbitals into different hybrid orbitals that is proper for the pairing of electrons to create chemical bonds in valence bond as per the atomic theory.

2. Cultured DNA molecules from different biological sources is recombinant DNA. They are the molecules are DNA molecules determining by laboratory techniques of genetic recombination to take mutually genetic material from various origins.

3. A process of breeding organisms because of their specific traits is selective breeding. It is the method that grants humans practice animal breeding and plant breeding to selectively develop selective over phenotypic traits
