How many ATP are produced in aerobic energy metabolism?

In aerobic conditions, the process converts one molecule of glucose into two molecules of pyruvate (pyruvic acid), generating energy in the form of two net molecules of ATP. Four molecules of ATP per glucose are actually produced, however, two are consumed as part of the preparatory phase.

How many ATP are produced in aerobic metabolism?

Aerobic vs anaerobic respiration

Products ATP, water, CO 2
Location Cytoplasm (glycolysis) and mitochondria
Stages Glycolysis (anaerobic), Krebs cycle, oxidative phosphorylation
ATP produced Large amount (36 ATP)

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). … This stage converts the NADH into ATP.

How are 36 ATP produced?

In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.

Does aerobic respiration produce 36 or 38 ATP?

ATP yield during aerobic respiration is not 36–38, but only about 30–32 ATP molecules / 1 molecule of glucose .

How are 32 ATP produced?

The NADH pulls the enzyme’s electrons to send through the electron transport chain. The electron transport chain pulls H+ ions through the chain. From the electron transport chain, the released hydrogen ions make ADP for an end result of 32 ATP.

How many ATP is 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.

Which molecule produces the most ATP?

So, oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.

What are the 3 stages of anaerobic respiration?

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

How much ATP is produced in etc?

A total of 32 ATP molecules are generated in electron transport and oxidative phosphorylation.

Why do eukaryotes only produce 36 ATP?

Why do eukaryotes generate only about 36 ATP per glucose in aerobic respiration but prokaryotes may generate about 38 ATP? A) eukaryotes have a less efficient electron transport system. … eukaryotes do not transport as much hydrogen across the mitochondrial membrane as prokaryotes do across the cytoplasmic membrane.

How many ATP can NADH make?

When electrons from NADH move through the transport chain, about 10 H +start superscript, plus, end superscript ions are pumped from the matrix to the intermembrane space, so each NADH yields about 2.5 ATP.

Why is the total count about 36 or 38?

Why is the total count about 36 or 38 ATP molecules rather than a specific number? Since phosphorylation and the redox reactions aren’t directly coupled to each other, the ratio of the number of NADH molecules to the number of ATP molecules is not a whole number.

What are examples of aerobic respiration?

Aerobic Respiration: It is the process of cellular respiration that takes place in the presence of oxygen gas to produce energy from food. This type of respiration is common in most of the plants and animals, birds, humans, and other mammals. In this process, water and carbon dioxide are produced as end products.

What is aerobic respiration formula?

The word equation for aerobic respiration is: glucose + oxygen → carbon dioxide + water (+ energy released) You need to be able to recognise the chemical symbols: C 6H 12O 6 + 6O 2 → 6CO 2 + 6H 2O.

What stage of aerobic respiration requires ATP?

Glycolysis: Occurs in the cytoplasm. First stage of both aerobic and anaerobic respiration. Requires 2 ATP to begin, and starts with glucose.
