What is ATP and how does it relate to cellular respiration?

ATP. Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.

How does lactic acid relate to ATP?

Figure \(\PageIndex{4}\): Lactic acid fermentation makes ATP in the absence of oxygen by converting glucose to lactic acid (through a pyruvate intermediate). Making lactic acid from pyruvate oxidizes NADH, regenerating NAD\(^+\) so that glycolysis can continue to make more ATP rapidly.

What role does ATP have in a cell what is the relationship between ATP and ADP?

ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell. When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).

Why is adenosine triphosphate ATP considered as the energy currency of the cell?

ATP is commonly referred to as the “energy currency” of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.

Where is the most energy released during cellular respiration?

the mitochondria
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).

How does adenosine triphosphate ATP become adenosine diphosphate ADP )?

If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. When it’s run down, it’s ADP.

What process produces adenosine triphosphate?

The process human cells use to generate ATP is called cellular respiration. It results in the creation of 36 to 38 ATP per molecule of glucose. The two ATP-producing processes can be viewed as glycolysis (the anaerobic part) followed by aerobic respiration (the oxygen-requiring part).

What are the metabolic processes in cellular respiration?

Cellular respiration is a collection of three unique metabolic pathways: glycolysis, the citric acid cycle, and the electron transport chain. Glycolysis is an anaerobic process, while the other two pathways are aerobic.
