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

-a rubber band shot through the air-kinetic energy

-wind blowing through a windmill-kinetic energy

-a stretched rubber band-kinetic energy

-water held behind a dam-potential energy

-water falling down a waterfall-kinetic energy

3.

-A nucleic acid molecule is constructed from nucleotide subunits-anabolic pathway

-photosynthesis generates storage carbohydrates from CO2 and H2O-anaabolic pathway

-Glycolysis converts one molecule of glucose to two molecules of pyruvate-catabolic pathway

-A lipid molecule is broken down into fatty acid subunits-catabolic pathway
