Question
1. Classify the following as examples of kinetic energy or examples of potential energy.
--muscle contraction
--glucose stored in liver cells
--ATP
-diffusion of molecules across the plasma membrane
2. Classify the following as examples of kinetic energy or potential energy
--gasoline sitting in a gas can
--a rubber band shot through the air
--wind blowing through a windmill
--a stretched rubber band
--water held behind a dam
--water falling down a waterfall
3. Identify whether the example describes an anabolic or catabolic pathway
-- A nucleic acid molecule is constructed from nucleotide subunits
--photosynthesis generates storage carbohydrates from CO2 and H2O
-Glycolysis converts one molecule of glucose to two molecules of pyruvate
--A lipid molecule is broken down into fatty acid subunits
Explanation / Answer
1.-muscle contraction-kinetic energy
-glucose stored in liver cells-potential energy
-ATP-kinetic energy
--diffusion of molecules across the plasma membrane-potential energy
2.
-gasoline sitting in a gas can-potential energy
