What else can I help you with?
Is electron transport the first step in the breakdown of glucose?
No, the first step in the breakdown of glucose is glycolysis, which occurs in the cytoplasm of the cell. Electron transport occurs later in the process, specifically in the mitochondria where the electrons produced in glycolysis are used to generate ATP.
Is there a pyruvate produced in glycolsis?
Nothing, pyruvic acid is the primary substrate used in gluconeogenesis or reverse glycolysis.
What is the six carbon molecule in the first step of cellular respiration and then converted onto?
The six-carbon molecule in the first step of cellular respiration is glucose. During glycolysis, glucose is converted into two molecules of pyruvate, which are three-carbon compounds. This process occurs in the cytoplasm and generates a small amount of ATP and NADH, which are used in subsequent stages of cellular respiration.
What is the sugar used in glycolysis?
Glucose is the sugar used in glycolysis. It is broken down into pyruvate during the process, generating ATP and NADH in the cytoplasm of cells.
How much ATP energy is invested in glycolysis?
2 ATP molecules are invested during glycolysis per each glucose molecule that is being metabolized. The first ATP molecule intervenes in the very first step, that is: from glucose to glucose 6-phosphate, catalyzed by a hexokinase, releasing an ADP molecule. The second ATP molecule is used in the third step: from fructose 6 phosphate to fructose 1,6-bisphosphate, catalyzed by a phosphofructokinase, and releasing also an ADP molecule.
Why does glycolysis take place?
Glycolysis takes place in cells to break down glucose into smaller molecules called pyruvate. This process produces ATP, which is used as an energy source for cellular activities. Glycolysis is the first step in both aerobic and anaerobic cellular respiration.
Is electron transport the first step in the breakdown of glucose?
No, the first step in the breakdown of glucose is glycolysis, which occurs in the cytoplasm of the cell. Electron transport occurs later in the process, specifically in the mitochondria where the electrons produced in glycolysis are used to generate ATP.
In glycolysis molecules of ATP are used in the first step and molecules of ATP are produced in the second step. (1 point) four two two four two two four four?
In glycolysis, two molecules of ATP are used in the initial steps, specifically during the phosphorylation of glucose and its conversion to fructose-1,6-bisphosphate. Subsequently, four molecules of ATP are produced during the later stages of glycolysis, resulting in a net gain of two ATP molecules. Thus, glycolysis is an energy-yielding process despite its initial investment of ATP.
What step in glycolysis consists of a phosphorylation reaction in which ATP is the phosphate source?
The sixth step of glycolysis, which involves the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate, consists of a phosphorylation reaction where ATP is used as the phosphate source. This step is catalyzed by the enzyme phosphofructokinase-1.
What molecules made during the later steps in fermentation is used in glycolysis?
Pyruvic acid is made during glycolysis and is later used in fermentation.
The first step in releasing the energy of glucose in the cell is known as?
The first stage in cellular respiration (releasing the energy from glucose) is known as glycolysis. This is a 10 step process. In many bacteria this is the only step that is down to release energy from glucose. The products of this step are two pyruvate and 4 ATP although 2 ATP are also used in this step, so in terms of net production 2 ATP are the result.
Is there a pyruvate produced in glycolsis?
Nothing, pyruvic acid is the primary substrate used in gluconeogenesis or reverse glycolysis.
What happen during glycolysis?
During glycolysis, a process that occurs in the cytoplasm of cells, glucose is broken down into pyruvate molecules. This process produces ATP and NADH, which can be used by the cell for energy production. Glycolysis is the first step in both aerobic and anaerobic cellular respiration pathways.
What is the sugar used in glycolysis?
Glucose is the sugar used in glycolysis. It is broken down into pyruvate during the process, generating ATP and NADH in the cytoplasm of cells.
What occurs during glycolysis?
During glycolysis, glucose is broken down into two molecules of pyruvate in a series of enzymatic reactions. This process takes place in the cytoplasm of the cell and results in the production of ATP and NADH, which can be used as energy sources for the cell. Glycolysis is the first step in cellular respiration and can occur with or without the presence of oxygen.
What molecule does fermentation provide to glycolysis?
Pyruvic acid is made during glycolysis and is later used in fermentation.
What stage of cellular respiration produces pyruvate as a product?
Pyruvate is produced at the end of glycoysis and converted into Acetyl CoA and then used in tricarboxylic acid (aka Kreb's, citric acid) cycle to ultimately more ATP.
