Cellular Respiration...

Description

Worksheet 13 Cellular Respiration Learning Objective. By engaging with this worksheet, you will be able to demonstrate the mechanisms of how glucose is processed into usable energy for the cell as ATP. (10 points) Evaluation. The worksheet will be graded as: Needs improvement Answers are missing or mostly incorrect.

0-5 points

Fair All answers are present, but many are incorrect. Drawings instead of models can earn a max of 7/10 if everything else is perfect. 6-7 points

Good Answers are mostly correct but superficial.

Exceptional Answers are 100% accurate, thorough, and creative.

8-9 points

10 points

Instructions. Answer the questions below. When you’re finished, upload your assignment into Blackboard as a .docx or .pdf (no .pages because I can’t view those). Drawings can be done instead of models but can only earn a max of 7/10 if everything else is perfect. Drawings can be done in many different ways. Pasted images taken from online will not be accepted. Part 1. Cellular and organismal context 1. Later in this worksheet, you will describe and model a part of cellular respiration. But first, pick one organism (other than the example) and cell type to model. Be creative! An example is provided, but do not use humans for your answers. Table 1. Questions

Part 2. Choose and model a part of cellular respiration 2. Next you will model one phase of cellular respiration. Identify which phase by circling one of the of the options below: 

Glycolysis



Pyruvate processing and the citric acid cycle

For whatever processes you choose not to model, please delete those instructions to make my reading and grading easier (and happier    )

If you’ve chosen Glycolysis... 3. Model how one molecule of glucose is processed during glycolysis. In Table 1 below, a. list the inputs and outputs of both phases of glycolysis b. create a model of each input and output with items you have around the house c. describe the enzymatic reactions that convert the inputs to the outputs for each phase d. I filled in a few boxes (in bold) and given you hints on what to put in the boxes (in parentheses) to help get you started. Replace the hints with new text or photos of your models/drawings. Table 1. Phases Moleculesfill in the blanks Input molecules:

Model (photo) of the molecule OR Description of the reactions

A. (photo of homemade model that demonstrates the number of carbons in this molecule)

B. (photo of homemade model)

a. glucose

Investment phase

b. 2 NAD+

Briefly describe the enzymatic reactions that occur during the investment phase of glycolysis: It transfers phosphate group and gets rearranged. It cleaves sugar into two different molecules. Conversion happens in both directions. G3P form mov e on (as quickly as it forms).

Output molecules: a. 2 pyruvate

A. (photo of homemade model that demonstrates the number of carbons in this molecule)

B. (photo of homemade model that demonstrates the number of carbons in this molecule)

C. (photo of homemade model of 2 ADP)

b. 2 NADH c. 2 ADP

Input molecules:

A. (photo of homemade model that demonstrates the number of carbons in this molecule)

B. (photo of homemade model of 2 NAD+)

C. (photo of homemade model)

a. 2 NADH b. 2 NAD+ c. 4 ADP

Payoff phase

Briefly describe the enzymatic reactions that occur during the payoff phase of glycolysis: G3P is oxidized, reducing NAD to NADH. (phosphorylation of the oxidized substrate). There’s a phosphate group transfer and it moves the phosphate group. It helps to form a double bound, and results in the loss of water from the molecule.

Output molecules: a. 2 pyruvates

A. (photo of homemade model that demonstrates the number of carbons in this molecule)

B. (photo of homemade model of 2 NADH)

C. (photo of homemade model)

b. 2 NADH c. 4 ATP
