Cellular Respiration

Cellular Respiration is the series of metabolic reactions that takes place in a cell that harvests chemical energy. The energy is converted from the stored chemical energy in molecules to the stored energy in ATP.

Stages of aerobic cellular respiration?

User Avatar

Asked by Wiki User

There are 3 processes in aerobic respiration. Glycolysis, Kreb's cycle, and electron transport chain.

A very, very simply, the equation for all those processes is Glucose + Oxygen = Energy + Carbon Dioxide + Water.

But I will describe all these steps a little more detailed for you:

Glycolysis:

1- one molecule of glucose is converted into pyruvate

2- pyruvate is converted into acetyl CoA and CO2

3- the acetyl-CoA enters the citric acid cycle (Kreb's Cycle)

4- 2 ATP molecules, 2 water molecules, and 2 NADH molecules are produced.

Kreb's Cycle:

5- Acetyl CoA is converted into citrate which then goes through a serious of chemical transformations, losing 2 carboxyl groups as CO2 (it is converted back to acetyl CoA by losing the 2 CO2 molecules which helps the production of citric acid)

6- citric acid is broken down and makes 2 molecules of CO2

7- After 2 complete cycles of the Kreb's cycle, 6 NADH molecules, 2 FADAH2 molecules, 2 ATP molecules, and 4 CO2 molecules are produced.

The Electron Transport Chain:

8- H+ electrons from molecules produced in previous steps (H+ removed from NADH, making it NAD+)

9- the H+ are combined with O2 molecules through different membrance transports and the electrical potential between all chemicals is used to generate ATP from ADP+phosphate

10- 32-34 molecules of ATP are produced

Overall, 38 molecules of ATP are generated for every molecule of glucose in the aerobic respiration steps.

Hope this helps. Sorry if I was unclear at any point.

Where does the produced pyruvate go in the second stage of cellular respiration?

Pyruvate enters mitochondria for further stages of cellular respiration such as Kreb's cycle and ETC.

When is cellular respiration performed?

User Avatar

Asked by Wiki User

cellular respiration is preformed when the cells need to obtain energy from glucose.

Where do the products in cellular respiration go?

User Avatar

Asked by Wiki User

The products of cellular respiration are water and carbon dioxide. The carbon dioxide is taken away from the cell by the bloodstream and carried to the lungs, where it is expelled when you exhale. The water simply becomes part of the water in your body. The human body is mostly water anyway.

What starts cellular respiration?

User Avatar

Asked by Wiki User

Cellular respiration begins with glycolysis that takes place in the cell's cytoplasm. Glucose is the substance that is burned for the production of energy.

What type of organisms are capable of cellular respiration?

Asked by Wiki User

Any cells that have mitochondria in them. This includes fungi, animal, and plant.

Does cellular respiration take in energy?

User Avatar

Asked by Wiki User

In order for cellular respiration to begin, two ATP molecules must be used up in order to breakdown the glucose molecule. Fortunately, the net gain of ATP from the first stage of cellular respiration, glycolysis, is 2 ATP. So even if oxygen is not present and fermentation has to occur, ATP is still made and not lost. However, if cellular respiration proceeds to the Krebs Cycle and carries out it's desired function, then a net gain of 36 ATP molecules will be made.

What do the process of photosynthesis and cellular respiration form?

The Processes Of Photosynthesis And Cellular Respiration Form Carbon Dioxide-Oxygen Cycle

Explain the differences and similarities of photosynthesis and cellular respiration?

User Avatar

Asked by Wiki User

Photosynthesis only happens in plants and fungi, while respiration happens with animals. In the process of photosynthesis, plants take in CO2 and water and they produce oxygen and glucose. In the process of respiration, animals take in the oxygen and glucose that the plants produce and release CO2 and water, which the plants take in. This all fit to become a cycle, which is why we and plants support one another. In the night, however, plants perform the process of respiration instead of photosynthesis. The similarities that they have is that they are both processes that provide the needs of life to the different organisms.

Why is 36 ATP molecules important to aerobic respiration?

User Avatar

Asked by Wiki User

First you have to know that respiration happens in 3 steps: glycolysis, Krebs cycle, and oxidative phosphorylation.

Glycolysis, through substrate-level phosphorylation, yields 4 ATP, but it uses up 2 ATP, giving a "profit" of 2 ATP.

The Krebs cycle also yields 2 ATP through substrate-level phosphorylation.

Oxidative phosphorylation occurs through the electron transport chain. This process yields about 34 ATP.

This gives us a total of about 38.

The total CAN be 36 depending on how much ATP is used by the shuttles that transport electrons from NADH in the cytosol. (The shuttle can use up 0-2 ATP)

What are the main similarities between cellular respiration and photosynthesis?

User Avatar

Asked by Wiki User

The main similarities between cellular respiration and photosynthesis is that they are both processes in which a cell produces glucose or energy. Both are used in your everyday environment. One difference is that photosynthesis happens in plants and cellular respiration in both plants and animals.

What 2 reactants are required for cellular respiration?

User Avatar

Asked by Wiki User

There are no 2 specific reactants. Many reactants can 'produce' energy. Gasoline, methane, ethane, propane, butane, etc all burn with a variety of oxidizers (oxygen it self being only one of them) and release heat energy.

What monosaccharide enters the process of cellular respiration?

User Avatar

Asked by Wiki User

Glucose is a sugar that provides energy for cellular respiration.During cellular respiration, a process called glycolysis occurs, converting glucose to pyruvate. The process releases high energy compoounds and is used for many purposes including respiration.
