ATP. Draw an ATP molecule and have an arrow pointing to the 'high-energy' bonds. See figure 6.13 for help.

Why is the reaction rate low at pH7? Be specific and say something about the enzyme structure at the molecular level!

Select all that apply. What are the functions of ATP?

Modified TRUE or FALSE. Write the word TRUE if the statement is correct. If the statement is false, write the incorrect underlined word/s and indicate the correct word/s to make the statement true. The Michaelis-Menten Constant (Km) of an enzyme is equal to the enzyme concentration at which the initial velocity of the reaction is one half of maximum velocity (Vmax).

Draw TCA Cycle.  Please make sure to state all the enzymes and co-factors for each step of the pathway.

Balance the reactions. A hint is provided to help you decide if the reaction will proceed as written, ie from left to right. Do not leave any fractions. 1. a) Balance Al₂O3 → Al + 0₂ b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: O₂ is very reactive) 2. a) Balance HNO3 + AI → b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: aluminum is a reactive metal, and a gas escapes) C7H14 + 0₂ 3. a) Balance, leave no fractions b) What type of reaction is this? c) Is this a redox rx, yes / no ? d) The reaction will go from left to right, yes / no ? (hint: O₂ is very reactive) H2(g) + AI(NO3)3 → CO₂ + H₂O

Cells and Membranes a. Give two examples of molecules that can pass through cell membranes without the need for energy, why can they do so?

atoms. 12 hydrogens, 6 oxuger Click or tap here to enter text.C atoms. 12) Back to the person who ate 300 grams of glucose, how many moles of glucose is this? Click or tap here to enter text. There are 2 moles. 13) If a person were to eat this much glucose all at once (that is a lot of sugar) and all this sugar enters the blood then the person's blood sugar concentration would rise. Imagine that all this glucose is released into the 5 liters of blood that circulate in this person. What would be the molarity of glucose in the blood? Click or tap here to enter text. 14) After each of these glucose molecules enter the blood they are uptaken through cell membranes to enter cells. Within these cells glucose is broken down in a series of steps releasing carbon dioxide along the way. For every molecule of glucose broken down how many molecules of carbon dioxide are created? Refer to the cellular respiration equation: Equation for Cellular Respiration: How to break down a carb C6H12O6 + 60₂ ➜…
