Distinguish between: - Glycolysis and TCA cycle.
Answers
Glycolysis
It occurs in the cytoplasm.
It is the first step of respiration. .
Glucose is broken down to form 2 molecules of puruvate.
It results in the liberation of 2 ATP and 2 NADH.
It is not connected with oxidative phosphorylation.
Citric acid cycle
It occurs in the mitochondria.
It is the second step of respiration
Water and carbon dioxide are formed from pyruvate.
Two molecules of acetyl Co-A oxidize to give 6 molecules of NADH and 2 molecules of FADH$$_2$4.
It is connected with oxidative phosphorylation.
Answer:
The main difference between glycolysis and Krebs cycle is:
Glycolysis
Glycolysis is determined as the chain of reactions, for the conversion of glucose (or glycogen) into pyruvate lactate and thus generating ATP. Glycolysis is the first step involved in the process of respiration and occurs in the cytoplasm of the cell. Glycolysis is the process in which one glucose molecule is broken down to form two molecules of pyruvic acid (also called pyruvate). The glycolysis process is a multi-step metabolic pathway that occurs in the cytoplasm of animal cells, plant cells, and the cells of microorganisms.
TCA cycle
Krebs Cycle is the second process of respiration which occurs in the mitochondria of the cell. Both are the process involved in respiration with the aim of fulfilling the energy requirement of the body.On the other hand, Kreb cycle or citric acid cycle involves the oxidation of acetyl CoA into CO2 and H2O.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.
