Topic 5: Cellular Energy

question

What are examples of autotrophs?
answer

plant, bacteria, some protists
question

What are examples of heterotrophs?
answer

fungi, animals, bacteria, some protist
question

The most instant form of energy is known as ________.
answer

ATP
question

Why is ATP a high energy molecule?
answer

The high energy molecule is because of the strength of the bond between the second and third phosphate groups. When it reacts with water it creates more energy than it takes to break the bond.
