Answer:
The correct answer is option 3. removal of hydrogen atoms from lactic acid.
Explanation:
In anaerobic conditions, it ferments to generate lactic acid. It is two way or reversible process in which oxidation of lactic acid produces pyruvic acid and NADH.
This process involves the removal of hydrogen atoms from the lactic acid and produces NADH and H⁺ in the presence of lactate dehydrogenase enzyme and convert into pyruvic acid.
Thus, the correct answer is option 3. removal of the hydrogen atoms from lactic acid.
Answer:
A. Helicases
B. Single strand binding proteins
C. Single strand binding protein
D. Topoisomerases
Explanation:
The helicases bind on the replication fork aiding in the unwounding of the DNA helix to allow for replication. The single strange binding proteins attach/bind to the separated single stranded DNA after the replication fork to prevent re-annealing of the single stranded DNA preventing Hydrogen bond formation that reanneals these two strands together. The topoisomerases are found just ahead of the replication fork preventing overwounding/ positive supercoils of the DNA. They do this by introducing breaks into the phosphate backbone of the DNA allowing them rotate forming negative supercoils and attaching the breaks once the DNA strand is relaxed.
