What happens if there is not enough oxygen for aerobic respiration?

Explanation: Aerobic respiration requires oxygen. In aerobic respiration, one molecule of glucose is broken down to produce 34 to 36 molecules of ATP, the energy currency of the cell. If there was no oxygen available, aerobic respiration would stop and organsims that rely on aerobic respiration would die.

How is glucose broken down if oxygen is not present?

Fermentation. Some organisms are able to continually convert energy without the presence of oxygen. They undergo glycolysis, followed by the anaerobic process of fermentation to make ATP.

Where does aerobic respiration break down glucose?

Well, let’s a look at how this happens the key organelle of aerobic respiration is the mitochondria. Now the first step in the break down of glucose is glycolysis which happens in the cytosol or the cytoplasm of the cell.

How is glucose broken down during respiration?

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.

Does glucose actually react with oxygen during cellular respiration explain?

Yes, during the process of cellular respiration, glucose is broken down into carbon dioxide and water with the help of oxygen. This produces energy, which is used for cellular metabolism.

Where does aerobic respiration take place?

mitochondria
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Where is the glucose broken down?

cytoplasm
Briefly: In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis. In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy “powerhouses” of the cells (Figure below).

Why is glucose broken down?

Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.

Where does the aerobic phase take place?

The process of aerobic cellular respiration takes place mostly inside of the mitochondria, an organelle that is known as the powerhouse of the cell.

Is glucose broken down in aerobic respiration?

Aerobic respiration breaks down glucose and combines the broken down products with oxygen, making water and carbon dioxide.

How does glucose react with oxygen?

The reaction of glucose, C6H12O6, with oxygen produces carbon dioxide and water.

Where does aerobic and anaerobic respiration takes place?

In the cell, Aerobic respiration occurs within the mitochondria of a cell, and the anaerobic respiration occurs within the cytoplasm of a cell.

What happens to glucose in anaerobic respiration?

In anaerobic respiration the glucose in muscle is converted to lactic acid: Anaerobic respiration occurs only in the cytoplasm of cells. Glucose is not completely broken down, so much less ATP is released than during aerobic respiration. The lactic acid that builds up needs to be oxidised to carbon dioxide and water.

What happens when glucose is broken down into energy?

When the chemical bonds of glucose are broken down into energy; carbon dioxide and water are generated as the byproducts. Energy in the form of ATP released through aerobic respiration can be simply described with the help of the following equations: Glucose + Oxygen = Energy + Carbon Dioxide + Water

Where does aerobic respiration occur in the body?

Aerobic Respiration Steps. The respiratory machinery is located in the cells of the body. During cellular respiration, the energy from glucose is released in the presence of oxygen. This process is scientifically known as aerobic respiration. Anaerobic respiration occurs in the absence of oxygen.

What is the role of cellular respiration in glycolysis?

Cellular respiration helps harvest chemical energy from food and store it in the ATP molecules. Glycolysis is the first step in aerobic respiration. This step is actually anaerobic as it does not require oxygen.
