Explain why 1 additional net ATP is produced when the beginning substrate is glycogen compared to glucose. In your answer provide the name of the enzyme responsible for this difference.

An enzyme (select all that apply)

1) is not altered by reaction with a substrate

2) is changed by reaction with a substrateis

3) made of carbohydrate

4) can be reused if not damaged

5) is made of protein

6) slows the rate of chemical reactions

7) increases the rate of chemical reaction

Select all that apply. An enzyme

1) is a carbohydrate

2) is a protein

3) is a biological catalyst

4) is changed by reaction with a substrate

5) is not altered by reaction with a substrate

6) can be reused if not damaged

7) increases the rate of chemical reaction

8) slows the rate of chemical reactions

9) lowers the activation energy of a reaction

10) increases the activation energy of a reaction

50. The table represents the rates of reaction at specific substrate concentrations for an enzyme that displays classical Michaelis-Menten kinetics. Two sets of inhibitor data are also included. Determine the Km and Vmax for the uninhibited enzyme.

[s](mM)        Without inhibitor    Vo (µM/s) With inhibitor A       With Inhibitor B

1.3                        2.50                      1.17                           0.62

2.6                        4.00                      2.10                           1.42

6.5                        6.30                      4.00                           2.65

13.0                      7.60                      5.70                           3.12

26.0                      9.00                      7.20                           3.58

Please Please Please....show detailed steps so I can repeat this with other problems. Need to be able to do without making a graph, thank you

What molecule or enzyme mediates the process of Translation?

Which molecule or enzyme mediates the process of Transcription?

Apparently our muscle cells are different from our nerve cells mainly because?

1. Which of the following is true regarding saturated fatty acids?

they contain one carbon double bond

they contain multiple carbon double bonds

they contain no carbon double bonds

they are the building blocks of nucleic acids

2. In anaerobic respiration (fermentation), one glucose can yeild 2 ATP's, and lactic acid is a by-product.

true or false

3. Which of the following is true regarding saturated fatty acids?

they contain multiple carbon double bonds

they contain one carbon double bond

they contain no carbon double bond

they are building blocks on nucleic acid

4. Which of the following is most important in determining what type of chemical bonds will form between atoms?

protons

neutrons

valence shell electrons

all of the above

5. Which of the following explains why water has a high surface tension, heat capacity, and heat of vaporization?

adjacent water molecules readily form covalent bonds with each other

water molecules are polar covalent thus form hydrogen bonds with each other

the non polarity of water

water molecules form ionic bonds with adjacent water molecules

Explain the process of forward and reverse transport of fatty acids and cholesterol and the role of cholesterol in the regulation of the transcription of the LDL receptor gene. Your answer should describe the relevant apolipoproteins and receptors

Blood Flow through Kidneys =       1,600 Liters/24 hours

Filtrate removed from blood =        180     Liters/24hours

Urine formed =         1.5       Liters/24hours

Table showing concentration of certain solutes in body fluids

            (All concentrations in mg/100ml)                                                         * in healthy kidney,

1a. Draw a simplified cartoon a nephron including structures at top of each column and any other structures you wish – be sure to label the structures! (you can skip the renal vein!).

1b Now look at how concentration of urea and protein change in various locations of the kidney – for each of these locations you need to contrast the concentrations and explain (hint: think about using the terms filtration/filtrate, reabsorption, and secretion…) what is happening to cause the changes you see in the table.

a. Compare and contrast urea/protein in the efferent arteriole:

b. Compare and contrast urea/protein in the capsule

c. Compare and contrast urea/protein in the collecting duct

d. Compare and contrast urea/protein in the renal vein

1c Concentration of amino acids and glucose in the renal vein is lower than in the incoming blood (for example in the afferent arteriole) – what is happening to these molecules in the kidney that is decreasing their concentration? (hint: notice they are not found in the urine!)
