1.) In the first step of glycolysis, the cell SPENDS an ATP and phosphorylates glucose as soon as it enters the cell. Why does the cell do this? Give two reasons!

2.) Speculate on why glycolysis, which is the beginning point of many catabolic pathways does not require oxygen.

Glycolysis

1)describe the Schiff-base role in aldolase

2)Describe the role of the thioester intermediate in G3P dehydrogenase

3) Describe the differences between glucokinase and hexokinase

4) Describe the reactants/products/regulation for the three irreversible reactions in glycolysis (1, 3, 10)

The claim is that the proportion of adults who smoked a cigarette in the past week is less than 0.25​, and the sample statistics include n=1906 subjects with 457 saying that they smoked a cigarette in the past week. Find the value of the test statistic.

In this experiment, we will explore fermentation. As you read Chapter 13, one of the fates of pyruvic acid can be the production of carbon dioxide and ethanol. The pyruvic acid is made from carbohydrate by glycolysis. By measuring the amount of CO2 made over time, you can measure the efficiency of glycolysis. The basic experiment is relatively simple. 1. Prepare a sample of carbohydrate in water. Take note of the concentration in % (use volume or weight). 2. Completely fill a small juice glass with the carbohydrate mixture. 3. Add yeast to the mixture. Start with 1.4 tsp. 4. Mix the carbohydrate, water, yeast mixture. If you spill some make sure the juice glass is filled to the brim. 5. Place a flat-bottom bowl over the juice glass. 6. Invert both the bowl and juice glass together, being careful not to spill the contents. Now the glass is upside down in the bowl. 7. Watch the glass for at least 2 hours, recording the size of the bubble formed every 15 minutes. The size of the bubble can be estimated by measuring the height of the bubble in cm. Multiply the height by (1/4)x(diameter in cm)x(diameter in cm) x pi. Pi is approximate 3.14. (V= h x pi x r^2). Run this experiment 4 times (Since there is a lot of waiting, you can start a second experiment after you get the first started). One experiment should be a control, using no carbohydrate. Vary only one variable. For example, one student might test sucrose (table sugar), Karo syrup, and honey. Another student might vary the concentration of carbohydrate; 5%, 10%, 15%. Another student might vary the temperature: in an ice bath, room temp, in a 100 degree F oven. This is a case where I would like to see you design your own experiment. Make a lab report of your own design. It should have the following components:

1. Introduction and Objectives.

2. Procedure (What did you do?).

3. Results in tabular form.

4. Conclusion ( What do your results mean in terms of what you have learned about enzyme kinetics, glycolysis, and carbohydrate metabolism?)

Which enzyme in each of the following pairs would be more limited in its catalytic scope?

A) An enzyme that exhibits linkage specificity or an enzyme that exhibits absolute specificity?

and

B) An enzyme that exhibits group specificity or an enzyme that exhibits stereochemical specificity?

using / for integral

Evaluate the double integral //R cos( (y-x)/(y+x) )dA where R is the trapezoidal region with vertices (1,0), (2,0), (0,2), and (0,1)

Referring to the definition of the Helmholtz energy (Eq. 6.5 in your text), show that dA represents the maximum amount of total work that a system can perform at constant T and V.
