8.1 and 8.2 Quiz 2023

James, Harper, and Avery are discussing about a physics concept. James says that energy is the ability to do work. Do you agree with James's definition of energy?

• Yes, energy is the ability to do work

• No, energy is the ability to produce ATP

• No, energy is the ability to store glucose

• No, energy is the ability to reflect green light

Ethan, Aiden, and Michael are studying for their biology exam. They come across a question about ATP. They want to know what is the key component of ATP that allows it to do work in our bodies, similar to how a battery powers a flashlight?

• Adenosine Diphosphate (ADP)

• Phosphate group

• Chlorophyll

• NADP+

What happens when cells release a phosphate molecule from ATP?

• ATP is converted into ADP

• ADP is converted into glucose

• ADP is converted into NADPH

• ADP is converted into water

During a science project, Harper, Lily, and Luna are trying to determine the main source of energy for cells. What do they find out?

• Light energy

• Heat energy

• Chemical energy

• Electricity

Evelyn and Benjamin are discussing how heterotrophs obtain the energy to produce ATP. Hannah suggests a real-world example. Which of the following examples best describes how heterotrophs obtain energy to produce ATP?

• By consuming other organisms, like a lion eating a gazelle

• By converting sunlight into ATP, like plants during photosynthesis

• By absorbing heat energy, like a reptile basking in the sun

• By converting glucose into ATP, like a car engine burning fuel

David is studying the green color of leaves and learns that it is due to a pigment present in chloroplasts. What is the name of this pigment?

• Chlorophyll a

• Chlorophyll b

• Chlorophyll c

• Chlorophyll d

During a biology class, Lily and Samuel learned about photosynthesis. They were asked to identify the organelle where photosynthesis takes place. Can you help them?

• Mitochondria

• Nucleus

• Chloroplasts

• Endoplasmic reticulum

Abigail, Ethan, and Lily are studying photosynthesis in their biology class. They are discussing the purpose of the light dependent reactions in photosynthesis. What is the main purpose of these reactions?

• To produce ATP

• To produce glucose

• To release oxygen

• To convert CO2 into sugars

Aria, Evelyn, and Charlotte are studying the process of photosynthesis. They are discussing the byproduct of the light dependent reactions in photosynthesis. What is the byproduct they are talking about?

• Glucose

• Water

• Oxygen

• ATP
