Is glycolysis a anabolic or catabolic reaction?
hey glycolysis is both an anabolic and a catabolic reaction, because at first, your are investing energy which is ATP, then you later harvest ATP with pyruvate (3C compound), and NADH. So it is both processes
What are the first stage of cellular respiration?
The first stage in cellular respiration is known as Glycolysis.
What does glucose need to enter the cell?
1. Glucose enters the cell by simple diffusion across the membrane. The addition of a bulky polar group like phosphate prevents it from diffusing right back out. 2. This is the first phosphate group that will contribute to the formation of glyceraldehyde-3-phosphate (GAP), an important intermediate in glycolysis.
An example of an enzyme?
Protein
Where is the pathway for cellular respiration located?
glycolysis it's the first stage, the rest of it occurs in the mitochondria.
What step in glycolysis consists of a phosphorylation reaction in which ATP is the phosphate source?
The first step
What reaction does the enzyme hexokinase catalyze?
First step of glycolysis- the phosphorylation of glucose to glucose-6-phosphate.
Name one reaction were ATP is required?
The first reaction of glycolysis, where glucose is phosphorylated (a phosphate group is added) to give glucose - 6 - phosphate requires ATP. This reaction is catalyzed by the enzyme hexokinase
3rd reaction of glycolysis. reactants, products, enzymes, reversibility?
Fructose-6-phosphate to fructose 1,6-bisphosphate. Phosphofructokinase (PFK). Requires ATP, Mg. First majorly regulated step of glycolysis. Irreversible
Describe the first reaction in glycolysis Is this reaction catalyzed by an enzyme?
Glucose is phosphorylated to form glucose-6-phosphate. ALL biochemical reactions occur only and exclusively through the action of enzymes.
Describe what happens where during the first step of glycolysis?
during the first step of glycolysis C6 is phosphorylated, turning it into a phosphate ester which is a low energy compound.
Which of these enzymes catalyzes the first reaction in glycolysis?
Hexokinase
Which step in glycolysis is the entry point for galactose?
Glycolysis is the break down of glucose in pyruate and release of energy here are the steps in which glycolysis occurGlucose ------> glucsose-6-phosphate -------> fructose-6-phosphate --------> fructose-1,6-bisphosphate --------> glyceraldhyde-3- phosphate and dihydroxyactone phosphate now dihydroxyacetone phosphate isomerize in glyceraldhyde-3- phosphate ----------- 2 glyceraldhyde -3- phosphate ------------> 1,3-bisphosphoglycerate ---------> 3-phosphoglycerate ----------> 2-phosphoglycerate -----------> phosphoenolpyruate ----------- pyruatein these reactions during reaction 1 and 3 ATP are changed into ADP and so these are called energy consuming reactions and in 7 and 10th step 2 ATP are released in both steps so forming 4 ATP and in end giving net gain of 2 ATP. So in glycolysis fructose is consumed after isomerisation and phosphorylating in 2nd step, Fructose also enter directly in glycolysis in some species which use fruit sugar fructose which first convert in Dfructose which is then phorphorylated in fructose-6-phosphate
The enzyme hexokinase catalyzes the first step of glycolysis, and is crucial to initiating the process and preventing the initial substrate from easily traveling out of the cell (as its pre-reaction structure is membrane permeable)?
Glucose, glucose-6-phosphate
What molecule is the reactant in the first reaction of glycolysis?

What are some examples of enzymes?
Hexokinase- This enzyme catalyzes the first reaction in glycolysis pathway.phosphotase- the enzyme that removes a phosphate group.Catalase- The enzyme that seperates peroxide (H2O2) into water and oxygen (H2O, O)As a rule of thumb, anything ending in the suffix -ase is 99.9% of the time an enzymeAmylase., Protease
