Unit 3 - Biochemical Processes Test Review

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction that undergo change to form products.

Front

What is the ultimate source of energy for life on Earth?

Back

Sunlight is the ultimate source of energy for life on Earth, as it is used in photosynthesis by plants.

Front

What is a monomer?

Back

A monomer is the smallest unit or building block of a larger molecule, such as glucose in carbohydrates.

Front

What happens to the rate of photosynthesis when carbon dioxide concentration decreases?

Back

The rate of photosynthesis decreases when carbon dioxide concentration decreases.

Front

What is spongy mesophyll?

Back

Spongy mesophyll is a layer of tissue in a leaf that contains air spaces for gas exchange and is involved in photosynthesis.

Front

What is a product in a chemical equation?

Back

A product is a substance that is formed as a result of a chemical reaction.

Front

What role does ATP play in living organisms?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the function of guard cells?

Back

Guard cells control the opening and closing of stomata, regulating gas exchange and water loss in plants.

Front

What is the difference between a monomer and a polymer?

Back

A monomer is a single building block, while a polymer is a large molecule made up of many monomers linked together.
