Explanation / Answer

35. Option D is correct.
Transformation in animal cells refers to the conversion of a normal cell into a tumor cell.

36. Option A is correct.
Glycolysis produces ATP via substrate level phosphorylation in fermentation.

37. Option E is correct.
All the given statements are true with respect to non-cyclic photophosphorylation.

38. Option D is correct.
An ideal antimicrobial agent should show a broad spectrum of activity.
