BIO 105 - Exam One Questions and Answers
Graded A+
Summarize the flow of energy through living systems and explain what happens to
most of the energy - CORRECT ANSWER-Physically: solar energy - chemical
energy: energy found in chemical bonds of carbohydrates, pats and proteins
mechanical energy: energy of motion = kinetic energy, position of an object before
it moves (potential energy)
energy from food - ATP - energy for cellular activities - ATP + P (phosphate)
Monomers - CORRECT ANSWER-individual units
Monomers of carbohydrates - CORRECT ANSWER-monosaccharides
Monomers of proteins - CORRECT ANSWER-amino acids
monomers of fats - CORRECT ANSWER-glycerol, fatty acids
Polymers - CORRECT ANSWER-Longer chains of multiple monomers (fats do
NOT form long chains)
, Polymers of carbohydrates - CORRECT ANSWER-polysaccharides
Polymers of proteins - CORRECT ANSWER-polypeptides
Polymers of fats - CORRECT ANSWER-triglycerides
Dehydration synthesis - CORRECT ANSWER-reaction that joins monomers
together to form polymers by removing water
Hydrolysis Reactions - CORRECT ANSWER-reaction that break polymers apart
into individual monomers by adding water
glucose - CORRECT ANSWER-preferred source for energy production
starch - CORRECT ANSWER-long-term energy storage in plants
glycogen - CORRECT ANSWER-short-term energy storage in animals
fiber - CORRECT ANSWER-forms structural components of leaves, stems, and
roots
carbohydrates - CORRECT ANSWER-provide long-term energy storage in
plants/animals, provide energy for life processes, and provide structural support
for plants
Triglycerides - CORRECT ANSWER-energy storage
Cholesterol - CORRECT ANSWER-cell membrane function, hormone
production
