Unit 3 Energy Flow Concepts 1 & 2

Front

What must all chemical reactions do?

Back

Break or form bonds.

Front

What is the process in which ATP is made and where does it take place?

Back

Cellular respiration occurs in the mitochondria.

Front

What decreases the activation energy needed for a chemical reaction?

Back

A catalyst.

Front

How would you describe an exothermic chemical reaction?

Back

It releases more energy than it absorbs.

Front

What happens during the enzyme substrate interaction when the enzyme is breaking bonds?

Back

The catalyzed reaction is releasing a product.

Front

What is a catalyst?

Back

A substance that increases the rate of a chemical reaction by lowering the activation energy.

Front

Define exothermic reaction.

Back

A reaction that releases energy, usually in the form of heat.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy carrier in cells.

Front

What is the difference between reactants and products in a chemical reaction?

Back

Reactants are substances that start a reaction, while products are substances formed as a result of the reaction.

Front

What is the significance of bond energy in chemical reactions?

Back

Bond energy is the amount of energy required to break a bond; it influences the stability of reactants and products.
