a) Diacyl phospholipids are made up of a modified glycerol and two ___________. These two building blocks are linked to glycerol by ______________ bonds.
b) One class of proteins is called enzymes. The enzymes ____________ specific chemical reactions. During a reaction the enzyme (circle best response) is or is not consumed.
Homework Answers
a) Diacyl phospholipids are made up of a modified glycerol and two fatty acid chains. These two building blocks are linked to glycerol by ester bonds.
An ester bond is a bond formed by the reaction between a hydroxyl group (OH) and a carboxyl(COOH) group. Here Hydroxyl group comes from glycerol and carboxyl group comes from the fatty acids.
b) b) One class of proteins is called enzymes. The enzymes catalyze specific chemical reactions. During a reaction the enzyme (circle best response) is not consumed.
A catalyst is a molecule which speeds up a reaction and it will not get consumed in the reaction.

Which statement about enzyme catalysis is false? All of the active site amino acids are next to each other in the primary sequence. Enzymes speed up reactions by forming specific non-covalent bonds between the enzyme amino acids and the transition state molecule. Some enzymes require other molecules, called cofactors, to carry out chemical reactions. Generally, the most important amino acids for an enzyme's function are those in the active site. Question 6 1 pt When [S] is much more than...

As early as 400 B.C., Greek philosophers proposed that matter was made up of particles. During the 1800s, John Dalton linked the idea of atoms with the chemical identity of an element. His atomic theory of matter involved the following postulates. 1. Each element is composed of extremely small particles called atoms. 2. All atoms of a given element are identical to one another in mass and other properties, but the atoms of one element are different from the atoms...
