Enzymes have an area on them known as the ACTIVE SITE. This active site is shaped to fit the substrate that will bind to it -complementary fit. Eventually, the bonds in the active site of the enzymes are ...

In replication, the main macromolecule in use is DNA, and the most important enzymes to this process are DNA Polymerase and DNA Helicase, so if no other macromolecule is mentioned and the...

The kidney is involved in osmoregulation (the control of blood water concentration): this is primarily controlled by the hormone ADH which is released from the pituitary gland in the brain when water conc...

Firstly, think of similarities between the processes. For example, neither process requires energy, so they are passive processes. This means that in both processes, molecules must move from a high concen...

Temperature can affect rate of reaction. As temperature increases, rate of reaction also increases, because enzymes have more kinetic energy. This continues up to the optimum temperature (for enzymes in h...
