Review from Lesson 1

Multiple Select

Which TWO elements are the most common in living things?

• Nitrogen

• Carbon

• Hydrogen

• Phosphorous

Multiple Choice

What is the main function of lipids?

• Store genetic information

• Provide insulation

• Store energy (short-term)

• Provide structure to cells and tissues

Multiple Choice

What is the main function of nucleic acids

• Store energy (short-term)

• Store energy (long-term)

• Provide genetic instructions

• Provide building blocks for cells and tissue

Multiple Choice

Which of these pairs represents the products of photosynthesis?

• Oxygen and water

• Glucose and oxygen

• Water and glucose

• Carbon dioxide and water

Multiple Choice

Which statement best describes the movement of carbon dioxide into or out of a plant during photosynthesis?

• Taken in from the soil

• Taken in from the air

• Released into the air

• Released into the soil

Multiple Choice

Which best describes the movement of energy in photosynthesis?

• Sugars are broken down and their energy is released

• Oxygen is absorbed and converted into water

• Energy is absorbed by leaves and converted into energy stored by glucose

• Oxygen is absorbed and converted into ATP

Multiple Choice

How is sugar (glucose) important in photosynthesis?

• Plants use carbon dioxide to break down sugar molecules

• Energy breaks down sugar molecules

• Sugar molecules are used as food by plants.

• Sugar molecules store energy (ATP)

Multiple Choice

Which of these pairs represents the reactants of photosynthesis?

• Oxygen and water

• Glucose and oxygen

• Water and glucose

• Carbon dioxide and water

Multiple Choice

The correct equation for photosynthesis is...

• carbon dioxide + oxygen -> glucose + water

• Oxygen + water -> glucose + carbon dioxide

• glucose + water -> carbon dioxide + oxygen

• carbon dioxide + water -> glucose + oxygen

Cellular Respiration Steps

• Larger glucose molecules are broken down into smaller molecules by using Oxygen

• Carbon dioxide and water are byproducts (waste)

• Energy (ATP) is also released and can be used by the cells

Multiple Choice

Which of the following is a product of cellular respiration?

• Radiant Energy

• Oxygen

• Glucose

• Water

Multiple Choice

Which of the following is a reactant of cellular respiration?

• Glucose

• Carbon Dioxide

• Water

• ATP
