In the first step of glycolysis,
A phosphate group is added at the 6th carbon location of the molecule resulting in the formation of Glucose-6-phosphate by the enxyme called hexokinase that uses ATP as an energy source.

what happens to the glucose molecule in the first step of glycolysis
What is the first catalyzed step in glycolysis and what are the important metabolic roles this step achieves for the transport of glucose and priming glycolysis?
. Explain what happens to glucose during glycolysis and respiration in terms of oxidation and reduction.
4. Explain what happens to glucose during glycolysis and respiration in terms of oxidation and reduction.
3. True or False [ ] In glycolysis, a single glucose molecule breaks down into two molecules of pyruvate, which can then be broken down further to release ATP. Glycolysis itself releases four net molecules of ATP per molecule of glucose. [ ] The main products in glycolysis include ATP, pyruvate and NADPH. [ ] In the preparatory phase of glycolysis, ATP is invested to convert glucose to fructose 1,6-bisphosphate. The bond between C-2 and C-3 is then broken to...
Draw out the transferase mechanism for first step of glycolysis (Glucose to G6p). Start with deprotonation and include the trigonal bipyramidal intermediate.
2. The first step in glycolysis is catalyzed by the enzyme herokinase: glucose + ATP glucose-6-P + ADP This reaction can be thought of as two coupled reactions (P is phosphate): (1) glucose + P + glucose-6-P (2) ATP + ADP + P For the overall reaction, AG" = -16.7 kJ/mol. For the hydrolysis of ATP (equation 2), AG = -310 kJ/mol. All reactions are performed at 37°C. (a) What is AGº for reaction 1? Iglucose - 6-11 if AG...

1. If one glucose molecule enters into glycolysis and proceeds through the PDC and through the citric acid cycle, how many NADH molecules are generated in these reactions? 2. If one glucose molecule enters into glycolysis and proceeds through the PDC and through the citric acid cycle, how many FADH2 molecules (that can be used directly by the ETC) are generated in these reactions? 3. If one glucose molecule enters into glycolysis and proceeds through the PDC and through the...

Hexokinase catalyzes the first step of glycolysis, in which glucose is phosphorylated to form glucose-6-phosphate. Which of these statements are accurate? The conformational shift that occurs when glucose, but nox water, enters the active site prevents water from hydrolyzing ATP Most kinases require the presence of a monovalent metal ion cofactor to prevent ATP hydrolysis. Hexokinase transfers the terminal phosphate of ATP to carbon 3 of glucose. Hexokinase consists of two domains, or lobes, that come together when glucose and...
