Where does the light and thermal energy given off when food burns come from?

• Light and thermal energy given off from burning food comes from the lighter used to light the food

• Light and thermal energy given off from burning food is converted from the chemical energy stored in the food

• Light and thermal energy given off from burning food comes from oxygen

• Light and thermal energy given off from burning is created when food burns

Why do two grams of fat provide a different amount of energy than two grams of carbohydrate?

• The number, type, and arrangement of atoms.

• Fat molecules are only made of hydrogen only.

• Carbohydrates never give off energy.

• Only the arrangement of atoms matter.

What is the same about carbohydrates, proteins, and fats? (Use the model)

• Carbohydrates proteins, and fats all have carbon, hydrogen, and oxygen atoms

• Carbohydrates proteins, and fats are all made of the same number and types of atoms

• Carbohydrates proteins, and fats all have the same arrangement and types of atoms

• Carbohydrates proteins, and fats can all form long chains of molecules

What is true about the breakdown of starch?

• Animals, but not plants, can break down starch

• Organisms break down starch into carbon, hydrogen, and oxygen atoms

• Organisms break down starch into carbohydrate subunits

• Starch breakdown is not a chemical reaction

When do humans store fat molecules in their bodies?

• Humans store fat molecules every time they eat anything that contains calories.

• Humans store fat molecules when they eat food with a lot of fat

• Humans store fat molecules when they eat junk food

• Humans store fat molecules when they eat more calories than they need

How do children use food molecules to grow taller?

• Children grow taller when they use food molecules they eat to build large molecules that make up new cells

• Children grow taller when they use the food molecules they eat to make up new cells without changing the food molecules

• Children grow taller when they use the energy from the food molecules, but all of the molecules leave the body as waste

• Children grow taller when they store food molecules as fat

Our body is always using energy, but we do not need to be eating all the time. Why is this true?

• Our body never uses energy so it does not matter when or if we eat.

• When we eat we store food for later. Our body uses the stored food later to give us energy.

• All we need to do is drink water to have energy

• The above statement is false we have to eat all the time( day and night) no matter what.

What is true about photosynthesis?

• During photosynthesis, plants convert thermal energy into chemical energy and store the energy in food molecules.

• During photosynthesis, plants use carbon dioxide and water in a chemical reaction to make glucose and oxygen

• Photosynthesis is a chemical reaction used by plants and animals to make food molecules

• Photosynthesis is the chemical reaction that plants use to get the energy to do things

What is true about why plants usually grow in soil?

• Plants use their roots to take in food from the soil

• Plants use their roots to take in non-food nutrients and water from the soil

• Plants use their roots to take in oxygen from the soil

• Plants use their roots to take in carbon dioxide from the soil

What do plants do with light energy during photosynthesis?

• Plants convert light energy into elastic energy to store in glucose molecules.

• Plants convert light energy into chemical energy to store in glucose molecules.

• Plants convert light energy into gravitational energy to store in glucose molecules.

• Plants convert light energy into electrical energy to store in glucose molecules.
