Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.



Thereof, what are the products of cellular respiration?

Cellular respiration is this process in which oxygen and glucose are used to create ATP, carbon dioxide, and water. ATP, carbon dioxide, and water are all products of this process because they are what is created.

Subsequently, question is, what is the overall reaction for cellular respiration? The overall reaction can be expressed this way: Glucose + 2 NAD+ + 2 Pi + 2 ADP → 2 pyruvate + 2 NADH + 2 ATP + 2 H+ + 2 H2O + heat. Starting with glucose, 1 ATP is used to donate a phosphate to glucose to produce glucose 6-phosphate.

Also question is, what are the 3 stages of cellular respiration and where do they occur?

Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.

What raw materials are needed for cellular respiration?

Oxygen and Glucose are the two main raw materials that are needed in cellular respiration.

What is the purpose of cellular respiration?

Cellular respiration is the process by which cells in plants and animals break down sugar and turn it into energy, which is then used to perform work at the cellular level. The purpose of cellular respiration is simple: it provides cells with the energy they need to function.

What is produced in cellular respiration?

Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

What are the products of glycolysis?

Glycolysis involves the breaking down of a sugar (generally glucose, although fructose and other sugars may be used) into more manageable compounds in order to produce energy. The net end products of glycolysis are two Pyruvate, two NADH, and two ATP (A special note on the "two" ATP later).

What are the 3 main parts of cellular respiration?

Aerobic cell respiration is divided by us into three parts in order to more easily see what is happening--Glycolysis, Krebs Cycle, and electron Transport System (ETS). We will explore these one at a time. GLYCOLYSIS: The breakdown of a glucose molecule (a six carbon chain) into two three-carbon pieces called pyruvate.

How do you explain cellular respiration?


Cellular respiration is what cells do to break up sugars to get energy they can use. This happens in all forms of life. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. Usually, this process uses oxygen, and is called aerobic respiration.

What happens during glycolysis?

Glycolysis is the process in which one glucose molecule is broken down to form two molecules of pyruvic acid (also called pyruvate). The glycolysis process is a multi-step metabolic pathway that occurs in the cytoplasm of animal cells, plant cells, and the cells of microorganisms.

How is ATP used in respiration?

ATP. Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP (Figure below). ATP, or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street.

What is ATP cycle?

The process of phosphorylating ADP to form ATP and removing a phosphate from ATP to form ADP in order to store and release energy respectively is known as the ATP cycle. Adenosine triphosphate is an energy source that is used in living things. ATP is created during cellular respiration.

What is fermentation and why is it important?

Fermentation is important in anaerobic conditions when there is no oxidative phosphorylation to maintain the production of ATP (adenosine triphosphate) by glycolysis. During fermentation, pyruvate is metabolised to various compounds such as lactic acid, ethanol and carbon dioxide or other acids.

Where do all the steps of cellular respiration occur?


Cellular respiration occurs in both eukaryotic and prokaryotic cells, with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes. There are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation.

What is the process of respiration?

Respiration is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (the currency of energy in cells). Note the number of oxygen, carbon dioxide, and water molecules involved in each 'turn' of the process.

How is ATP generated?

Although cells continuously break down ATP to obtain energy, ATP also is constantly being synthesized from ADP and phosphate through the processes of cellular respiration. Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP.

How many ATP are produced in cellular respiration?

Cellular respiration produces 36 total ATP per molecule of glucose across three stages. We can describe each stage's ATP production. The first stage, glycolysis, occurs in the cytosol and nets 2 ATP when splitting the six carbon glucose into two three-carbon fragments.

What is NADH in biology?


Flavin adenine dinucleotide, or FADH2, is a redox cofactor that is created during the Krebs cycle and utilized during the last part of respiration, the electron transport chain. Nicotinamide adenine dinucleotide, or NADH, is a similar compound used more actively in the electron transport chain as well.

How are photosynthesis and cellular respiration the same?

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

What is the importance of cellular respiration?

In cellular respiration, cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP.
