Chapter 3 discusses six important factors that influence protein requirements for physically active and inactive people. Please list these six factors. 

True or False: Of the energy substrates (carbohydrates, proteins and fats), only the amino acids that make up proteins contain nitrogen. 

Using the calculations discussed in Chapter 3 reading and lecture, please calculate the following. Please show all of your work. Points will be awarded/docked based on work shown.  Tim is a 18 year old male distance runner. He is 5’11” and weighs 160 lbs. Calculate an appropriate total daily protein intake range for him. 

What amino acid appears to be the most potent stimulator of protein synthesis?

Let q represent “I get an A,” let r represent “I eat bananas,” and let p represent “It is Tuesday.”  Write the following compound statement in symbols (using p, q and r): It is Tuesday, and if I eat bananas, I do not get an A.

Which area represents (A ∩ B’) ∩ C

Question 5 (10 pts): Signal multiplication. Plot discrete signals x[n] (3 points) , h[n] (3 points) , and y[n]=x[n] · h[n] (4 points) where, x[n] = u[n + 3] − u[n − 3] h[n] = 2 · (1/2)n · u[n]

Question 2 (10 pts = 10 questions x 1 point each) Determine if each statement True (T) or False (F). Write T or F clearly. “White Noise” affects all frequencies equally. The product of a bounded function and an unbounded function is not always unbounded. Biosignals are used in the detection and treatment of pathologies. DC offset is scaling of signal in amplitude. Any signal can be decomposed into odd and even parts. Electrocardiogram (ECG) is an example of a bio-optical signal. Magnetoencephalogram is a measurement of varying magnetic fields. In the transform x(at), a < 1 will stretch the signal x(t) on the time axis. In a general exponential signal x(t) = C eat, C can be complex. For a system to be stable, a bounded input signal should lead to a bounded output only for future time.
