QUESTIONS AND ANSWERS WITH
SOLUTIONS 2024
- ANSWER nucleic acids in all cells
pH scale - ANSWER Acidic: 0-6.9
Neutral: 7
Basic (alkaline): 7.1-14
acidity - ANSWER amount of hydrogen ions in a solution (called pH)
acids vs. bases ions - ANSWER acids- more H+
bases- more OH-
macromolecules - ANSWER sequence of simple molecules; all composed of C, H, and O
types of macromolecules - ANSWER carbohydrates, proteins, lipids, and nucleic acid
elements in DNA - ANSWER contains the same elements as other macromolecules, except it has N and P
monomers of complex carbs - ANSWER glucose, fructose, galactose
types of complex carbohydrates - ANSWER starch, cellulose, chitin,
function of complex carbs - ANSWER function to get energy to cell so if can carry out activities
cellulose - ANSWER carbohydrate that make plant cell walls
, chitin - ANSWER carbohydrate that makes exoskeleton of insects
carb loading - ANSWER excess carbs stored in muscles as glycogen and broken down when blood glucose
is low
peptide bond - ANSWER covalent bond formed between amino acids
protein functions - ANSWER 1. structural
2. protective- antibodies
