I have to identify whether the following are primary active transport, secondary active transport, or passive transport. Then I have to decide what is the energy source: a chemical reaction, concentration gradient of cotransported ion, or conc gradient of transported solute. Below are my...

I checked my answers and I do not undersand why some of them are incorrect.

what are the correct steps for the mechanism of chymotrypsin? Below is my answer but I don't know if it is right. a) His 57 catalyzes removal of H from Ser 195 hydroxyl. b. Ser 195's nucleophilic O attacks carbonyl C of substrate. c. His 57 donates H to N of sissile peptide bond...

thank you of replying! Yes, I did a wrong calculation for part 1, the answer is 4.76m/s for part 2, I did (4.76m/s)^2= 2x9.8xh so h= 1.16 and then to find angle I did cos theta= length -h/ length so theta is cos^-1= 2-1.16/2= cos^-1 (0.42) theta= 65.2 degress is this correct for...

1. a mass m1=5g moving to the right at a speed of 100m/s undergoes a perfectly inelastic collision with a block of wood, m2= 100g, at rest. what is the speed just after the collision? 2. if the mass and block of wood described in question #1 are parts of a ballistic pendulum of length 2m...
