The lock and key theory suggests that there is a complimentary shaped substrate that will fit exactly into the specific shape of the enzyme's active site. In this case, amalyase is the enzyme and the subs...

Using conservation of momentum, m1u1 + m2u2 = m1v1 + m2v2, set m1 = 2kg, m2 = 3kg, u1 = 5m/s, u2 = -4m/s and v1 = -4m/s. Substitute these into the equation to get 25 + 3(-4) = 2*(-4) + 3*v2 10 - ...

To start, the equation to use can be identified as the capactior discharge equation V(t) = V_maxe^-t/RC. From here, we can see that this equation can be solved to give capacitance, and...

The initial [-OH] is 0.250M since NaOH releases 1 mole of -OH per mole of base. Using Kw=[H+][-OH], [H+]=(110^-14)/0.250=410^-14M (note remember units). Hence the initial pH=-...

All proteins are polymers of amino acids arranged with varying degrees of complexity. The most basic structure is the order of amino acids, this is called the primary structure. Amino acids form peptide b...
