How many overall ATP’s are produced per glucose in an aerobic cellular respiration?
Determine the molecular weights of glucose and urea respectively.
Fatty acids such as lauric acid and palmitic acid and oleic acid are long unbranched carboxylic acids consisting of 12 to 20 carbon atoms. Which type of fatty acid should people avoid ingesting, saturated or unsaturated and why?
Which of the following is NOT a catabolic pathway or reaction?
Assume that an enzyme-catalyzed reaction follows Michaelis-Menten kinetics with a Km = 1 μM. The initial velocity is 0.1 μM/min at 10 mM substrate. Calculate the initial velocity at 10 μM substrate.
The molecular weight (molar mass) of the enzyme trypsin is 25 kDa. In a kinetic experiment, we find that trypsin (2.0 μg) catalyses the hydrolysis of 3.3 μmol of a given substrate in 5 min, in a total incubation volume of 3.0 mL. Compute the enzyme activity (μmol/s), specific activity (μmol/s*μg) and turnover number (per s).

If one gallon of blood was added in three gallons of water, and one ounce of that dilution was added to 9 ounces of water, what is the final dilution when 7 mL of that dilution is added to 563 mL of water?
In the study of fats and lipids, determine which of the two triglycerides has a higher melting point, Substance A – containing only lauric acid and glycerol, or Substance B – containing only stearic acid and glycerol.
An enzyme hydrolyzed a substrate concentration of 0.03 mmol/L, the initial velocity was 1.5 x 10-3 mmol/L min-1 and the maximum velocity was 4.5 x 10-3 mmol/ L min-1. Calculate the Michaelis constant.
