Does cellular respiration produce 36 or 38 ATP?

The theoretical maximum yield of ATP for the oxidation of one molecule of glucose during aerobic respiration is 38. In terms of substrate-level phosphorylation, oxidative phosphorylation, and the component pathways involved, briefly explain how this number is obtained.

How is 36 ATP produced in cellular respiration?

Electron transport from the molecules of NADH and FADH2 made from glycolysis, the transformation of pyruvate, and the Krebs cycle creates as many as 32 more ATP molecules. Therefore, a total of up to 36 molecules of ATP can be made from just one molecule of glucose in the process of cellular respiration.

Where is 36 ATP produced?

Cellular respiration produces 36 total ATP per molecule of glucose across three stages.

How is 34 ATP produced?

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). The electron transport chain takes place in the mitochondria.

Why do we use 36 ATP instead of 38?

In many human cells, two NADH+H+ molecules are transformed to FADH2 during this transport, thus giving 2 fewer ATP molecules at the end (36 rather than 38).

How many ATP are produced from nadh2?

1 ATP is synthesized using 4 protons; approximately 3 ATPs are produced from one $NAD{H_2}$ molecule. Hence, the correct answer is option (C), That is one molecule of $NAD{H_2}$‚Äč on oxidation yields 3 ATP molecules.

How are 38 ATP produced?

Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. … Biology textbooks often state that 38 ATP molecules can be made per oxidized glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).

How do we get 32 ATP?

In a eukaryotic cell, the process of cellular respiration can metabolize one molecule of glucose into 30 to 32 ATP. The process of glycolysis only produces two ATP, while all the rest are produced during the electron transport chain.

How many ATP are produced by nadph2?

When electrons flow from higher to lower side ATP liberate from ADP by enzyme ATP synthase. In this process also the formation of 3ATP takes place. So, the correct answer is 3 ATP.

How many ATP are produced in glycolysis?

During glycolysis, glucose ultimately breaks down into pyruvate and energy; a total of 2 ATP is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi –> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.

How many ATP molecules are produced when 2nadh2 of glycolysis?

In the second half of glycolysis, energy is released in the form of 4 ATP molecules and 2 NADH molecules.

How many ATP and NADPH2 are produced in light reactions?

The nine molecules of ATP and six molecules of NADPH come from the light reactions.

How many stages are there in cellular respiration?

three stages
The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3). Figure below gives an overview of these three stages, which are further discussed in the concepts that follow.

How is 4 ATP produced in glycolysis?

Results of Glycolysis

Energy is needed at the start of glycolysis to split the glucose molecule into two pyruvate molecules. … As glycolysis proceeds, energy is released, and the energy is used to make four molecules of ATP. As a result, there is a net gain of two ATP molecules during glycolysis.

How much ATP is produced in each energy system?

Total 38 ATP

From this we can see how the aerobic energy systems capacity to generate ATP is virtually limitless. Where the anaerobic glycolytic system synthesises only two ATPs from the breakdown of one glucose molecule, the aerobic system can synthesise 38 ATPs from one molecule, albeit very slowly in comparison.

How many ATP Net are made in the glycolysis part of cellular respiration?

2 net ATPs
Aerobic cellular respiration is divided into four stages: Glycolysis – 2 net ATPs (4 are actually produced, but since 2 are used up in the start of respiration, we say that it produces 2 net ATPs) Formation of Acetyl Coenzyme (or Oxidation of Pyruvic Acid) – no ATPs.

What are the 4 stages of cellular respiration?

The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

What are the 3 stages of cellular respiration?

Summary: the three stages of Aerobic Respiration

Carbohydrates are broken down using all three stages of respiration (glycolysis, citric acid cycle and the electron transport chain).
