What process occurs in structure H?

What process occurs in structure H? Chloroplasts are the sites of photosynthesis. Photosynthesis produces glucose and releases oxygen into the atmosphere.

What process occurs in structure H Chapter 6?

Terms in this set (13) What process occurs in structure H? Photosynthesis produces glucose and releases oxygen into the atmosphere.

What process occurs within Box B a scheme of cellular respiration at Box A which is located in the cytosol glucose turns into pyruvate with release of ATP and electrons carried by NADH pyruvate from this stage is used in a cycle in box B which is located in the mitochondrion as a result ATP CO2 and electrons?

Glycolysis. In glycolysis, glucose —a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule.

How does pyruvate enter a mitochondrion ()?

Pyruvate is a charged molecule, so in eukaryotic cells it must enter the mitochondrion via active transport, with the help of a transport protein. Pyruvate is broken down into three CO2 molecules, including the molecule of CO2 released during the conversion of pyruvate to acetyl CoA.

How much NADH does glycolysis produce?

Overall, glycolysis produces two pyruvate molecules, a net gain of two ATP molecules, and two NADH molecules.

What is the basic function of fermentation?

The main function of fermentation is to convert NADH, a chemical compound found in all living cells, back into the coenzyme NAD+ so that it can be used again. This process, known as glycolysis, breaks down glucose from enzymes, releasing energy.

What happens when no oxygen is present for respiration?

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 is the name of the process in which glucose is converted to pyruvate?

Glycolysis is a linear metabolic pathway of enzyme-catalyzed reactions that converts glucose into two molecules of pyruvate in the presence of oxygen or two molecules of lactate in the absence of oxygen.

What are the 7 steps of cellular respiration in order?

Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made.

  • Glycolysis.
  • Pyruvate oxidation.
  • Citric acid cycle.
  • Oxidative phosphorylation.

Is glycolysis aerobic or anaerobic?

Glycolysis, as we have just described it, is an anaerobic process. None of its nine steps involve the use of oxygen. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell.

What are the three steps of aerobic cellular respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.

What is the main function of pyruvate?

Functions of Pyruvate The primary function of the molecule is to act as the transport molecule that carries carbon atoms into the mitochondria for complete oxidation to carbon dioxide.

What is required for pyruvate to enter the mitochondria?

The transport of pyruvate into the mitochondria is via the transport protein pyruvate translocase. Pyruvate translocase transports pyruvate in a symport fashion with a proton, and hence is active, consuming energy.. Upon entry to the mitochondria, the pyruvate is decarboxylated, producing acetyl-CoA.

What two pathways can pyruvate enter?

Pyruvate is a key intersection in the network of metabolic pathways. Pyruvate can be converted into carbohydrates via gluconeogenesis, to fatty acids or energy through acetyl-CoA, to the amino acid alanine, and to ethanol. Therefore, it unites several key metabolic processes.
