Cell & Molecular Bio of the Human Body (A&P)

Why are cells of the body described as "functional" units?

• They allow for the structural framework of the body

• They have different jobs to perform

Which carbon containing substances primarily make up cells and allow for their functionality?

• Organic molecules

• Inorganic molecules

• Salts

All of the following are major classes of biological molecules except

• Amino acids

• Carbohydrates

• Lipids

• Nucleic acids

• Proteins

Which type of biological molecule does NOT form macromolecules?

• Carbohydrates

• Lipids

• Nucleic acids

• Proteins

What is the monomer of carbs?

• Monosaccharides (sugars)

• Glucose

How do carbs like glucose allow for short term energy?

• They allow ATP molecules to be made in cellular respiration

• They allow O₂ to be made in photosynthesis

Why is ATP important for the functioning of the human body?

• It allows for chemical, mechanical, and transport work

• It speeds up biochemical reactions by lowering activation energy

Many glucose molecules bond together to form a _

• Polymer

• Polysaccharide

_ allows for glucose storage in animals (like humans). It is stored in _

• Glycogen, muscles & liver

• Glycogen, adipose tissue

• Starch, muscles & liver

• Starch, adipose tissue

Which polysaccharide is broken down in digestion?

• Cellulose

• Starch
