Question

The chemical reactions involved in respiration are virtually identical between prokaryotic and eukaryotic cells. In eukaryotic cells, ATP is synthesized primarily on the inner membrane of the mitochondria. Where are the corresponding reactions likely to occur in prokaryotic respiration?

A) in the cytoplasm
B) on the inner mitochondrial membrane
C) on the endoplasmic reticulum
D) on the plasma membrane

Answer 1

In prokaryotic respiration, the corresponding chemical reactions to ATP synthesis are likely to occur on the plasma membrane.

Step-by-step explanation:

In prokaryotic respiration, the corresponding chemical reactions to ATP synthesis are likely to occur on the plasma membrane.

The electron transport system (ETS), which is involved in cellular respiration, is embedded in the cytoplasmic membrane of prokaryotes. This system comprises a series of membrane-associated protein complexes and electron carriers. These carriers transfer electrons from NADH and FADH2 to generate an electrochemical gradient across the plasma membrane, which is then used to make ATP by oxidative phosphorylation.

Therefore, the correct answer is D) on the plasma membrane.
