Trypsin and pepsin are both enzymes in the digestive system which catalyze the breakdown of proteins in food into smaller peptide chains or into individual amino acids. However, like other enzymes, they differ in their substrate and optimal conditions. Analyze the
graph and select ALL of the statements that accurately describe the action of trypsin and pepsin.

A)
Trypsin has an optimal pH of 8.
B)
Pepsin works best at a pH of 3.
Both enzymes have an optimal pH of 7
D)
Pepsin works best in more acidic conditions.
E)
Trypsin works best in more acidic conditions,

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
