Binding of the first molecule of oxygen changes the tertiary/quarternary structure of Haemoglobin - this can be referred to as a conformational shift. This change in structure then exposes another binding...

The concentration is higher in the soil. The process of active transport is used to move molecules against the concentration gradient (from a low to a high concentration). Therefore the concentration of i...

PCR takes place in three stages - denaturation, annealing, and extension. The process begins with a very small quantity of DNA being loaded into a PCR machine. The hydrogen bonds that exist between the tw...

Neurons are the basic cells in the nervous system. They are made up of a soma, axon, dendrites and synapse. The synapse is the end part of the neuron that is in charge of sending a message from one neuron...
