It is false that constellations are only visible in certain seasons due to the revolution of the Earth toward the constellation.
For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.
Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis.
In geneal enzyme have a pH optimum. However the optimum is not the same for each enzyme.
The commonly used site to feel a pulse is radial artery on the wrist, the point where radial artery approaches the wrist present at the middle of wrist.
When we placed our fingers in the middle of wrist, we can feel the pulse wave. That is 72 beats per minutes. The radial artery is the site of insertion of the arterial line, for monitoring the blood pressure. It is selected because it is accessible due to the low incidence of the complications such as thrombosis.
The pressure of the blood is always high in the arteries comparative to the veins, usually arteries are present deep in the body, the radial artery in only artery that approaches the skin. Hence, it is used to monitoring the pulses.
