THE KREBS CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In Kreb’s Cycle ____
A
Energy is stored in the formed of ADP
B
Energy is release from ADP
C
Energy is release from ATP
D
Energy is stored in the form of ATP
Explanation: 

Detailed explanation-1: -The Krebs cycle is the second stage of cellular respiration. During the Krebs cycle, energy stored in pyruvate is transferred to NADH and FADH2, and some ATP is produced.

Detailed explanation-2: -Krebs Cycle is a part of Cellular Respiration Cellular respiration is a four-stage process. In the process, glucose is oxidised to carbon dioxide and oxygen is reduced to water. The energy released in the process is stored in the form of ATPs. 36 to 38 ATPs are formed from each glucose molecule.

Detailed explanation-3: -In the Krebs cycle, two ATP, six NADH +H+, and two FADH2 were produced. A net of four ATPs was produced from glycolysis through the Krebs cycle. More ATP will be produced from reduced coenzymes in the mitochondria during the electron transport chain and oxidative phosphorylation.

Detailed explanation-4: -The Krebs cycle is the second phase in cellular respiration. It occurs in the mitochondria in the cell. The number of ATP molecules produced in the Krebs cycle is 2.

Detailed explanation-5: -ATP provides for example energy for muscle contractions and can therefore be referred to as “energy currency” of the cells. Before the fuel molecules can be inserted in the Krebs Cycle, they must first all be converted into acetyl-CoA.
