### Enzymes and Reaction Types in GlycolysisIn glycolysis, identify the enzyme and type of reaction (REDOX/group transfer/C-C make it or break it/isomerization/etc) that:- **Requires energy input from ATP** (name one)- **Reduces NAD⁺**- **Are essentially irreversible in the cell** (name two)- **Is the committed step** ### ExplanationThe content is asking to identify specific enzymes involved in glycolysis based on their functions or the type of reaction they catalyze. Glycolysis involves a series of enzymatic reactions that break down glucose into pyruvate, generating energy in the form of ATP and NADH.

Glycolysis is the process of conversion of one molecule of glucose into two molecules of pyruvate.…

Here is the diagram for glycolysis. Use the numbers by each step to identify: (enter only one single digit number for each) There may be more than one correct answer for each. an endergonic reaction an exergonic reaction a redox reaction substrate level phosphorylation
The reaction pictured is an oxidation-reduction reaction in the citric acid cycle in which the energy-carrier molecule NADH is generated. Identify which molecule in the reaction will be oxidized and which molecule will be reduced. Place a single answer choice in each box. COO- HO-C-H H-C-H COO- Malate NAD+ NADH + H+ Oxidized malate oxaloacetate COO- H-C-H ī COO- Oxaloacetate Reduced NADH NAD+
Two reactions are shown below. These reactions are directly coupled in cells by an enzyme called hexokinase, which is a key enzyme in glycolysis. It is generally the case that reactions that are directly coupled by enzymes share some common reactants. What is the net reaction when these two reactions are combined? Glucose + Inorganic Phosphate + ATP + Water → Glucose 6-phosphate + ADP Glucose + ATP + Water → Glucose 6-phosphate + ADP + Inorganic Phosphate Glucose + ATP → Glucose 6-phosphate + Inorganic Phosphate Glucose + ATP → Glucose 6-phosphate + ADP
For each of the statements below about the dUTPase enzyme, mark whether it is true or false. If it is false, change the language to make the statement true. _______If the dUTPase enzyme is the rate determining step in a larger metabolic pathway, the reaction likely lies near to equilibrium and is irreversible. _______For the dUTPase reaction, it is not likely that DG’ = DG°’ _______ dUTPase has a higher affinity for its substrate than for its product, but both of these are higher than the affinity for the transition state _______Kinetic analysis of dUTPase using Michaelis-Menten methods assumes that the formation of the E*S complex has a large negative value for DG
Break down the glycolysis pathway in terms of the following reaction steps (you may write or take photos of chemical reactions; be sure to include the enzyme involved): - ATP-requiring steps - ATP-producing steps - NAD-involving steps, and - Irreversible steps
Review the following statements and discuss whether each one is correct, incorrect or partially correct: Con In the presence of oxygen glycolysis can yield a net production of 6 molecules of ATP per molecule of glucose. In the presence of oxygen glycolysis can yield a net production of 8 molecules of ATP per molecule of glucose. In the absence of oxygen glycolysis can yield a net production of 2 molecules of ATP per molecule of glucose. In the absence of oxygen glycolysis can yield a net production of 4 molecules of ATP per molecule of glucose
Which of the following statements best explains why the activity of ATP-citrate lyase and malic enzyme are often paired together? The use of ATP by ATP-citrate lyase means that NADH needs to be regenerated cytosolically so that more ATP can be generated via shuttle systems and replace the ATP used by ATP-citrate lyase ATP-citrate lyase produces ATP and malic enzyme produces NADPH, both needed in the fatty acid biosynthetic pathway The activity of ATP-citrate lyase and malic enzyme never are correlated, they always function in different realms of metabolism The generation of acetyl CoA is a substrate for fatty acid synthesis in the cytosol and NADPH is generated as the anabolic electron carrier
