BCS 205 Human Physiology EXAM 1
questions with verified answers
graded A+
What is a Biomolecule? - correct answer ✔✔biochemicals that have a biological function
What are the 4 major Biomolecules? - correct answer ✔✔carbohydrates
lipids
proteins
nucleotides
What are the functions of Biomolecules? - correct answer ✔✔energy in food fuel body
What are the main types of chemical bonds? - correct answer ✔✔ionic & covalent
Anabolic vs Catabolic - correct answer ✔✔a: negative-reaction creates more chemical bonds
c: positive- increase reaction rate by lowering activation energy
Hydrophobic vs. Hydrophillic - correct answer ✔✔phobic- water hating
phillic- water loving
Are the following molecules polar/non-polar? - correct answer ✔✔carbohydrates-polar
water-polar
oxygen-polar
, proteins-depends on r group
lipids- non-polar
phospholipids- polar head, non-polar tail
Polar - correct answer ✔✔p: equal number of protons and electrons but now the electrons are
shared which creates and unequal distribution of charges
Non-polar - correct answer ✔✔2 non-metals have the same electronegativity, they both tug on
electrons & share them equally
Function of Carbohydrates - correct answer ✔✔insulation; cushions organs
Function of Proteins - correct answer ✔✔building blocks, work horse, neurotransmitters,
hormones
Function of Lipids - correct answer ✔✔fatty cushion
Normal Blood Sugar Range - correct answer ✔✔60-100 for glucose
What is main source of energy for human body? - correct answer ✔✔glucose
Where is glycogen stored? - correct answer ✔✔liver & muscles
What carries oxygen around the body? - correct answer ✔✔hemoglobin
Where is tRNA located? - correct answer ✔✔cytosol
