Competitive inhibition occurs when a Question 19 options: A) substrate binds to an enzyme in the active site and activates the enzyme. B) molecule binds to an enzyme at a site other than the active site and inhibits the substrate from binding C) molecule binds to an enzyme but doesn't change the shape of the active site. D) molecule binds to an enzyme in the active site and prevents the substrate from binding.

what is the question here. i think you messed up.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
