At the optimum temperature for a given enzyme (specific to each enzyme dependent on the composition of the protein), catalytic activity is at a maximum and hence the reaction proceeds at maximum rate. Bot...

Water potential is a measure of the tendency of water to move from one place or compartment to another. Water moves based on the water potential, from a region of higher water potential to a region of low...

The lock-and-key mechanism of enzyme activation involves the active site of the enzyme fitting perfectly with the substrate molecule and the subsequent reaction being catalysed biologically. However, the ...

Firstly, it is important to recap how DNA codes for synthesis of proteins. mRNA is formed from complementary base pairing to the template strand of DNA in a process called transcription. Every 3 bases wit...

The resting potential of a neurone is -70 mV, which means that it's more negative in the cytoplasm than in the tissue fluid. In the membrane there are sodium-potassium pumps which work using active trans...
