Chapter 8.1 - Energy and Life

What is the role of ATP in cellular activities?

• ATP provides energy for active transport

• ATP is used for the synthesis of proteins and nucleic acids

• ATP is involved in the movement of organelles throughout the cell

• All of the above

Where do plants get the energy they need to produce food?

• From the sun

• From consuming other organisms

• From ATP

• From glucose

What is the main difference between autotrophs and heterotrophs?

• Autotrophs obtain energy from the sun, while heterotrophs obtain energy from food

• Autotrophs are plants, while heterotrophs are animals

• Autotrophs use ATP, while heterotrophs use glucose

• Autotrophs can make their own food, while heterotrophs cannot

What is the chemical formula of glucose?

• C₆H₁₂O₆

• C₅H₁₀O₅

• C₂H₁₂O12

• C₆H₁₀O₅

What happens when a phosphate group is removed from ATP?

• ATP becomes ADP and releases energy

• ATP becomes AMP and releases energy

• ATP becomes AMP

• ATP becomes ADP

Why do most cells only have enough ATP for a few seconds of activity?

• ATP is not good at storing energy for the long term

• ATP is constantly replenished by the cell

• ATP is quickly used up by cellular activities

• ATP is converted into glucose for long-term energy storage

What is the principal chemical compound that cells use to store and release energy?

• ADP

• AMP

• ATP

• Glucose

What is the function of ATP in active transport?

• ATP is used for the active transport of molecules across the cell membrane

• ATP provides energy for the movement of organelles throughout the cell

• ATP is involved in the synthesis of proteins and nucleic acids

• ATP is used for the movement of cilia and flagella
