Question

Lab 4: Pathway Building - Glycolysis Theory based lab focusing on key mechanisms within the glycolysis pathway (dry) Lab Objectives: Examine the structural components of the transformation of carbohydrates into energy Compare the differences in the reverse process to recreate carbohydrates for storage. Part 1 - Designing your worksheets Before we get into the actual poster building, we will first go through a series of questions designed to prepare you for the final version when we use the poster sheets. To begin, we will fill in the following diagram with steps learned from this week's worksheets (attached). Question 1: (10 points) Fill in boxes labelled Q1 on worksheets 7 and 8 with its corresponding structures and enzymes, Red boxes indicate structures, black boxes indicate enzymes Gluconeogenesis does not alway use the same enzymes to go in the reverse direction of glycolysis. Question 2: (3 points) List the steps that are unique to Gluconeogenesis Question 3: (3 points) Provide an explanation for why different steps in this process are needed. Although this pathway starts with glucose, the majority of sugar that we take in is not glucose. Apart from starches, humans take in a large amount of sugar as sucrose (table sugar), lactose from milk, and fructose from corn syrup. Let's breakdown each of these sugars and figure out how they build into our map Let's start with breaking down each of these sugars

Answer 1

Que ? There are basically three steps which are unique in cogenesis i.e. not common steps which are a in glycolysis of glucose. These three sters are as follows: are also found ol. conversion of pyruvate to phosphoenolp youuv. osphoenolpyruunte via here, Pyruvate convento to phosphoenolpyouro on oxa'once atate intermediate. ATP ADP pyourate u oxoloncetate Pyruvate carboxylase carboxylinase hoe Phosphoenolpysuunte (PEP) GTP / PEP 02. conversion of fructose-1,6-bisphosphate foructose - G. phosphate fructose - 1,6-bisphosphate - - Foructose -1,6- bisphosphatase 03 conversion of glucose-6-phosphate gluose - 6- phosphate gluwie glucose-6- phosphatase * I would like to highlight the fact that in pluwreogenesis the conversion of one renetant to the other produs is neuprocul do plycolysis i.e. in glycolysis PEP convento to pyruvate but inglv woneogenesis pyruvate convent to PSP. Nothing is different except reco reciprocality but the steps are unique in gluconeogenesis from the next in terms of enzymes used and intermediate is used to achieve that reciprocality.

Since in the given question, the fill in boxes labelled Q1 on worksheets 7 and 8 with its corresponding structures and enzymes are not attached which is necessary to answer the first question i.e. question 1. Thus, I answered the next question which is question no. 2.

And also, the given question is a type of question with multiple questions (question 1-3) and according to HomeworkLib guidelines under the given condition answer only the first question unless the student has not specified (which is not in the given case). Thus, I answered only the second question i.e. Question 2.
