End-products of aerobic respiration are

Detailed Solution for Test: Electron Transport System & Oxidative Phosphorylation (Aerobic Respiration) - Question 1

Aerobic respiration is the complete oxidation of sugars in presence of oxygen.

The carbohydrates are broken down into CO₂ and H₂O and this releases energy. This energy is stored in the form of ATP and later used in the body.

So, the correct option is 'Carbon dioxide, water, and energy'.

NCERT Topic: Aerobic respiration

NCERT Line: "C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy"

The end-product of oxidative phosphorylation is​

Detailed Solution for Test: Electron Transport System & Oxidative Phosphorylation (Aerobic Respiration) - Question 2

The NADH carries electrons to the oxidative phosphorylation step of cellular respiration, which occurs inside of the mitochondrion Water (H2O) and ATP (energy carrier) At the end of electron transport, oxygen is the final electron acceptor, and it combines also with hydrogen ions to form H2O.

NCERT Topic: Electron transport system (ETS) and oxidative phosphorylation

NCERT Line: "The passing on of the electrons removed as part of the hydrogen atoms to molecular O₂ with simultaneous synthesis of ATP."

Detailed Solution for Test: Electron Transport System & Oxidative Phosphorylation (Aerobic Respiration) - Question 3
  • In ETS cytochromes (electron acceptors), ATP synthesis are arranged in series of Cyt b - c1 - c - a - a3.
  • Cytochromes are the electron carriers in different electron transport complexes in the membrane of the mitochondria which help in the formation of ATP by the process of oxidative phosphorylation.
  • The sequence of the movement of the electrons include cytochromes b, cytochrome c, cytochrome a, and cytochrome a3.

Energy equivalent of NADH is how many number of ATP molecules?​
Detailed Solution for Test: Electron Transport System & Oxidative Phosphorylation (Aerobic Respiration) - Question 4

Each NADH molecule theoretically yields 3 ATP molecules during chemiosmosis. However, in some tissues, NADH requires more energy to cross the mitochondrial membrane and some of its potential is lost.

NCERT Topic: Electron transport system (ETS) and oxidative phosphorylation

NCERT Line: "Oxidation of one molecule of NADH gives rise to 3 molecules of ATP."

Oxidative phosphorylation involves simultaneous oxidation and phosphorylation to finally form
Detailed Solution for Test: Electron Transport System & Oxidative Phosphorylation (Aerobic Respiration) - Question 5

Krebs cycle occurs inside the matrix of mitochondria.The cycle is also known as the citric acid cycle or tricarboxylic acid cycle. It includes stepwise oxidative and cyclic degradation of activated acetate derived from pyruvic acid.

NCERT Topic: Oxidative phosphorylation

NCERT Line: "The passing on of the electrons removed as part of the hydrogen atoms to molecular O₂ with simultaneous synthesis of ATP."
