Question

Electron transport system in mitochondria is located on _____
(a) Outer membrane
(b) Inter cristae space
(c) Inner membrane
(d) Inner membrane space

Answer 1

Dear Student,

◆ Answer - (C)

Electron transport system in mitochondria is located on Inner membrane of mitochondrion.

◆ Mitochondria -

• The mitochondrion is a double-membrane bound organelle found in most eukaryotic organisms.
• It's known as powerhouse of the cell.
• It is site Krebs cycle and beta-oxidation of compounds.
• Inner membrane of mitochondria provides enzymes for electron-transport chain.

Hope this helps you. Thanks for asking..

Answer 2

Answer:

(c) Inner membrane

Explanation:

The electron transport chain is a mitochondrial pathway in which electrons move across a redox process from NAD+/NADH to O2/H2O. Inner membrane of the mitochondria consists of proteins and complex molecules that involves in the process of electron transport. The electron transport system,  accepts energy from carriers  and stores it that can be used to phosphorylate ADP. Two energy carriers donate energy here, one is nicotine adenine dinucleotide (NAD) and the other is flavin adenine dinucleotide (FAD). Reduced NAD carries energy to complex I (NADH-Coenzyme Q Reductase). FAD is a bound part of the succinate dehydrogenase complex (complex II).
