Biology 189 Exam 1 Chapter 1-4 Questions With Complete
Solutions
3 Macronutrients Correct Answers 1. carbohydrates: broken
down into simple sugars used to build cell.
2. Proteins: break down into amino acids.
3. fats: broken down into fatty acids and glycerol.
4 primary comments of cell membrane Correct Answers 1.
phospholipids
2. cholesterols
3. proteins
4. glycocalyx
Activation energy Correct Answers energy to get the reaction
going.
active site Correct Answers part of an enzyme that binds to
substrate.
Active transport Correct Answers involves transport of
molecule against the concentration gradient; requires ATP

All living things have five things in common: Correct Answers
1. Grow
2. Metabolism
3. homeostasis
4.Reproduction
5. sense/response stimuli
, Anecdotal evidence Correct Answers informal observation that
hasn't been systematically tested; interesting but often
unreliable.

harm cells.
Atoms (building block) Correct Answers smallest unit of and
element.

(polymer made of sugars and amino acids)
Carbohydrates Correct Answers A chain of sugar monomers
and hydrophilic.
catalysis Correct Answers process of speeding up the rate of a
chemical reaction (by enzyme).
