Enzymes are biological catalysts which speed up the rate of reactions. They are specific to their substrate (seen in the lock and key model) and form enzyme-substrate complexes. At low temperatures the enzym...

In response to high blood glucose concentrations, insulin is released from the pancreas into the blood. Insulin acts on cells (especially liver cells) and causes glucose to move from the blood into these cel...

An enzyme is a biological catalyst. As temperature is raised, the rate of the reaction increases up to the optimum temperature, the point at which the enzyme works the best. Beyond this, raising the temperat...

Bacteria in the water decay organic matter in sewage -> respire aerobically -> uses the O2 in the water and reduces O2 concentration -> fish have less O2 to aerobically respirate -> fish die

The net diffusion of water from an area of high concentration to low concentration across a partially-permeable membrane. 3 key elements to the definition1) Diffusion of water2) high conc to low conc3) parti...
