In glycolysis ATP molecules are produced by .?

In glycolysis, ATP molecules are produced by? a- oxidative phosphorylation b-substrate-level phosphorylation c-cellular respiration d-photophosphorylation e-photosynthesis


In glycolysis what is the first three carbon compound produced?

Two molecules of pyruvate are created from one molecule of glucose.


What is produced because of the glycolysis reaction?

The first stage of cellular respiration is glycolysis. It is an anaerobic process that is initiated by 2 ATP molecules and a glucose molecule. The end products are 2 NADH molecules, 2 molecules of pyruvic acid, and a net gain of 2 ATP molecules.


How many molecules of ATP are produced in each type?

The first step of fermentation is glycolysis, which produces a net gain of 2 molecules of ATP. Fermentation produces no additional ATP.


How many ATP molecules are produced in each type of fermementation?

The first step of fermentation is glycolysis, which produces a net gain of 2 molecules of ATP. Fermentation produces no additional ATP.


Which stage of respiration occurs whether or not oxygen is present?

Glycolysis literally means "splitting sugars." Glucose, a six carbon sugar, is split into two molecules of a three carbon sugar. In the process, two molecules of ATP and two "high energy" electron carrying molecules are produced. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP. This process is called fermentation.


What is used up during the first step of glycolysis?

Two ATP molecules


If the cell uses 2 ATP molecules at the of Glycolysis how does it end up wth a net gain of 2 ATP molecule?

In the first phase of glycolysis, the cell uses 2 ATP molecules. Then during the process of glycolysis, the cell produces 4 ATP molecules, making the net gain at 2 ATP molecules.


How many ATP molecules are produced by the electron transport chain by glycolysis?

A net of two ATP are produced during glycolysis.


What is The first stage of the breakdown of sugar molecules for energy?

The first stage of the breakdown of sugar molecules for energy is glycolysis. The sugar molecules are broken down by enzymes, releasing energy in the process.


In glycolysis the first few steps require energy from two ATP molecules. The net gain of ATP molecules at the end of this pathway is?

2 ATP molecules


How does glycolysis contribute to cellular respiration?

Glycolysis is the first stage in cellular respiration. It converts glucose into 2 pyruvate, which then moves into the Krebs Cycle. Glycolysis is anaerobic and takes place in the cytoplasm.
