Passive membrane processes are those that do not require energy and move substances down a concentration gradient; namely, these are diffusion, facilitated diffusion and osmosis.
Because soap is more basic, adding the acidic solution of lemon juice will decrease the pH value and cause it to become more acidic.
1. The binding of an inhibitor can stop a substrate from entering the enzyme's active site and/or hinder the enzyme from catalyzing its reaction. Inhibitor binding is either reversible or irreversible. Irreversible inhibitors usually react with the enzyme and change it chemically (e.g. via covalent bond formation).
2. Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds.
