DRAW IT Using a series of arrows, draw the branched metabolicreaction pathway described by the following statements, andthen answer the question at the end. Use red arrows and minussigns to indicate inhibition.L can form either M or N.M can form O.O can form either P or R.P can form Q.R can form S.O inhibits the reaction of L to form M.Q inhibits the reaction of O to form P.S inhibits the reaction of O to form R.Which reaction would prevail if both Q and S were present inthe cell in high concentrations?(A) L S M(B) M S O(C) L S N(D) O S P

Can you explain the answe?

= Cellular Respiration Glucose (Cs) 2 G3P (Cs) 2 U Cs) 2 GTP- GDP (Cs) 2 acetyl CoA (___Cs) 1½/202 iii H₂O iv 2 Fill out the diagram as indicated by instructions below. Label processes g. A, B, and C. h. Some reactions are labeled with numbers in blue ovals. (Some of these are "collected" reactions, i.e. they stand for all reactions of the same type that occur in the same part of the pathway.) Among these reactions, write in reactants and products for all reactions that involve ATP and ADP. i. Reactions 6 and 8 involve FADH₂. Write in reactants and products for these reactions. j. Among the reactions labeled with numbers in blue ovals, write in reactants and products for all reactions that involve NAD+ and NADH. k. Below, write in the molecules that correspond to each of the following labels (iv is a molecule moving through the protein, indicated with an arrow): i: ii: iii: iv: 1. The blank in front of molecule (i) that you identified above is to indicate how many copies of this…

Many enzyme mechanisms involve transferring protons. Sidechains of an enzyme can act as catalytic acids or catalytic bases in this process. The figure below shows a step in the reaction by the enzyme triose phosphate isomerase. Glu165 group. -OH Would a catalytic acid gain or lose a proton? Which sidechain in the mechanism is acting as a catalytic acid? co CH,OPO, 2- Activity remaining (%) Would a catalytic base gain or lose a proton? Which sidechain in the mechanism is acting as a catalytic base? 100 Curve I 8 Glu¹65 9 Below are two pH rate profiles showing the percent activity as a function of pH. Answer the questions below about how these curves relate to the mechanism of triose phosphate isomerase. Remember what fraction of a titratable group is unprotonated at the pka. 10 OH In this reaction a carbonyl is converted into an enol intermediate. Circle the enol 100 Activity remaining (%) H Curve 2 CIOH CIOH CH₂OPO,²- 8 9 N N 10 7 pH PH i) Which of these curves shows the pH rate…

The 2 eynzymes are affected by a substrate. Choose all correct answers.

A dichotomous key works by determining positive and negative reactions to different biochemicals. Why does this method allow us to identify one species of organism from another? – for this question, do not describe the dichotomous key procedure, think about why it works, what are biochemical reactions based on? Think enzymatic pathways, what are enzymes, what are they a reflection of? Keep the answer between 2-3 sentences

At the left is an energy diagram that shows the energy changes for the example of glucose (C6H1206) being converted to CO2 + H2O. One curve is the reaction with enzymes, while the other is without enzymes. For these reactions, the "X" indicates: Glucose + 60g a) b) free energy of glucose free energy of activation without enzymes free energy of CO2 + H2O free energy released free energy of activation with d) e) Progrem af reaction enzymes Frec energy, G

Consider the reaction catalyzed by PFK. In the presence of ATP, which of the following will be expected? Select all that apply. The T-state is stabilized The rate of the reaction is enhanced. The initial velocity plot would show a shift in the curve to the right The quaternary structure of PFK is stabilized to promote efficient binding of substrate
