Butterflys feed on nectar from flowers that are made of a watery solution of sugars (fructose, glucose, and sucrose). What type of macromolecule does the butterfly need to survive if this is its diet?

• Nucleic Acid

• Lipid

• Carbohydrate

• Protein

Eating a food high in fats (lipids) would provide the body with what benefit?

• Short term energy source

• High cholesterol

• The ability to pass on genetic

• long term energy storage

What purpose does a nucleic acid macromolecule provide for the body?

• Provides long term energy

• Tells the cell how to operate with its genetic information

• provides short term energy

• Provides important amino acids for cell function

Based on the following diagram showing that the products (things produced) from photosynthesis are the reactants (things that start the reaction) for cellular respiration and vice versa... which of the following best describes this important relationship?

• They both take place using energy from the sun

• One happens during the day the other happens at night

• They cannot happen at the same time

• They are opposite reactions

The chemical reaction of photosynthesis is as follows: 6CO2 (carbon dioxide) + 6H20 (water) --> C6H12O6 (glucose) + 6CO2 (oxygen) Which of the following is a product of photosynthesis?

• Sunlight

• Carbon Dioxide

• Glucose

• Water

How do organisms use ATP to power their body cells in the process of cellular respiration?

• The organism breaks the chemical bonds in ATP to capture energy

• The organism breaks down the chemical bonds in the ATP to release the energy

• The organism uses sunlight to produce oxygen from ATP

• The organism uses sunlight to produce carbon dioxide from the ATP
