Detailed explanation-1: -The Krebs cycle is the main source of energy for cells and is a crucial part of aerobic respiration. It consumes pyruvate to produce carbon dioxide, ATP, NADH, and FADH. The first product formed in the cycle is citric acid. Thus it is also known as the citric acid cycle.

Detailed explanation-2: -tricarboxylic acid cycle, (TCA cycle), also called Krebs cycle and citric acid cycle, the second stage of cellular respiration, the three-stage process by which living cells break down organic fuel molecules in the presence of oxygen to harvest the energy they need to grow and divide.

Detailed explanation-3: -What is the Krebs Cycle? Also known as the citric acid cycle, the Krebs cycle or TCA cycle is a chain of reactions occurring in the mitochondria, through which almost all living cells produce energy in aerobic respiration. It uses oxygen and gives out water and carbon dioxide as products.
