Which substance is the reactant in glycolysisg?
The primary reactant in glycolysis is glucose. During this metabolic pathway, glucose is broken down into pyruvate, producing energy in the form of ATP and NADH in the process. Other sugars can also enter glycolysis, but glucose is the main substrate.
Which sugar or sugars are substrates for glucose oxidase?
Glucose oxidase primarily acts on glucose as its substrate. It catalyzes the oxidation of glucose to gluconic acid while producing hydrogen peroxide. While glucose is the main substrate, some forms of the enzyme can also act on other sugars, such as D-fructose, but with significantly lower efficiency.
What are the substrate for fermentation?
The substrates for fermentation are typically carbohydrates, such as glucose or sucrose. These sugars are broken down by microorganisms like yeast or bacteria to produce energy in the form of ATP and fermentation byproducts like ethanol or lactic acid.
What stage follows glycolysis?
The stage that follows glycolysis is the citric acid cycle, also known as the Krebs cycle. This cycle takes place in the mitochondria and is responsible for further breaking down glucose to produce more ATP and other important molecules.
What is substance used in respiration?
Glucose is used as the substrate. Oxygen is used to oxidize glucose

Why only glucose enters into glycolysis why not other sugars directly enter into glycolysis?
Other sugars do enter into glycolysis such as fructose, galactose and mannose. Fructose can directly enter into glycolysis while the other two is converted to a glucose intermediate molecule because it can produce the two triose phophate molecules (DHAP and G3P) which are needed to generate energy from the reactions (ATP) and pyruvate.
How many molecules of ATP are gained by substrate-level phosphorylation from the complete breakdown of a single molecule of glucose in the presence of oxygen?
In substrate level phosphorylation, the ADP is phosphorylated directly by the transfer of phosphate group from substrate. If we consider glucose, then we get four substrate level phosphorylated ATPs, net gain of two in glycolysis and other two are formed when the two pyruvate molecules formed after glycolysis enter the TCA cycle.
How many ATP molecule produced in Glycolysis?
There are two net molecules of ATP produced by substrate-level phosphorylation during glycolysis. (when one molecule of glucose is respired). Two are used to convert the glucose molecule to fructose, but four are released when pyruvate is made. However, the other products of glycolysis enable the Link Reaction, Krebs cycle and Oxidation Phosphorylation to happen, and these release a lot of ATP.
The Krebs cycle take place within the?
The Krebs cycle takes place in the mitochondria of cells. It is a series of chemical reactions that are part of cellular respiration, where energy is generated from the breakdown of glucose and other molecules.
What is the net production of ATP in the Krebs cycle?
The Krebs cycle generates approximately 30 ATP molecules per glucose molecule respired.The actual number varies, because varying amounts of energy are diverted into other processes than ATP synthesis.For a discussion of some of the issues, visit:http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/C/CellularRespiration.html#citric_acid
Is nadph formed during the Krebs cycle?
Definitely! Per ever glucose that passes through cellular respiration, 6 NADH are produced during the Krebs Cycle. (Precisely, 3 NADH are produced per turn of the Krebs Cycle and 1 glucose molecule causes the Krebs Cycle to turn twice. Therefore, 2 turns * 3 NADH per turn = 6 NADH)

How ketogenic amino acid converted to glucose?
Ketogenic amino acids are converted into acetyl-CoA, which can enter the Krebs cycle to produce ATP or undergo ketogenesis to produce ketone bodies. Acetyl-CoA cannot be converted back into glucose directly, as it bypasses the steps of gluconeogenesis. Glucose can be synthesized from non-ketogenic amino acids or other substrates through gluconeogenesis in the liver.
What is substance used in respiration?
Glucose is used as the substrate. Oxygen is used to oxidize glucose
What is the substrate for isomerase?
The substrate of dipeptides is a peptide. These peptides are small proteins comprised of short chains of amino acid monomers bonded by other peptides that occur naturally in biological organisms
