Which of the stages of cellular respiration can occur without the other?

Which of the stages of cellular respiration can occur without the other?

During cellular respiration, electrons move through a series of electron acceptor molecules. Which of these stages of cell respiration can occur without the others? glycolysis. The waste products of cellular respiration include ________.

What are the 4 cellular respiration stages?

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

What stage does cellular respiration occur?

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).

What is the only anaerobic stage of cellular respiration?

Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen.

What happens if cellular respiration is not occurring properly inside your body?

Without the process of cellular respiration, there is no gaseous exchange and the cells, tissue and other organs die due to the lack of oxygen and by the accumulation of carbon dioxide within the cells and tissues.

What are the stages of cellular respiration and where do they occur?

Cellular respiration is the process in which cells break down glucose, release the stored energy, and use it to make ATP. The process begins in the cytoplasm and is completed in a mitochondrion. Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

What happens to cellular respiration when there is no oxygen?

When oxygen is not present and cellular respiration cannot take place, a special anaerobic respiration called fermentation occurs. Fermentation starts with glycolysis to capture some of the energy stored in glucose into ATP. Some bacteria carry out lactic acid fermentation and are used to make products such as yogurt.

What will happen if respiration stop?

For most people, it’s safe to hold your breath for a minute or two. Doing so for too much longer can decrease oxygen flow to the brain, causing fainting, seizures and brain damage. In the heart, a lack of oxygen can cause abnormalities of rhythm and affect the pumping action of the heart.

What can go wrong with cellular respiration?

The downside of respiration is that it inevitably generates nasty byproducts called free radicals, which not only are harmful to the mitochondria but can also damage cells generally — not to mention deprive them of the energy they need to function properly.

Which is the first stage of cellular respiration?

In the process of glyoclysis, 2 molecules of ATP, 2 molecules of pyruvic acid and 2 “high energy” electron carrying molecules of NADH are produced. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of aerobic cellular respiration.

What happens when glycolysis is done without oxygen?

Sugar Rush. Glycolysis can also occur without oxygen, a process called anaerobic respiration, or fermentation. When glycolysis occurs without oxygen, cells make small amounts of ATP. Fermentation also produces lactic acid, which can build up in muscle tissue, causing soreness and a burning sensation.

What happens to glucose in anaerobic respiration without oxygen?

Without oxygen, anaerobic respiration is able to convert glucose into lactic acid, and release a small amount of energy – 2 ATP. Think back to the glycolysis step of aerobic respiration; the process is the same for anaerobic respiration, except the end product is not pyruvate, but lactate.

Where does most of the ATP in cellular respiration occur?

Most ATP generation occurs during the electron transport chain and oxidative phosphorylation stage of cellular respiration.
