Biochemistry & Cells

One component that is similar in all four types of biomolecules is they all _____.

• have the same molecular shape

• have the same chemical composition

• contain the element carbon

• contain the element nitrogen

Which of the answers below correctly places the building block with the correct biomolecule?

1.Nucleic Acid

2.Lipid

3.Protein

4.Carbohydrate

• 1=amino acids

• 2=fatty acids

• 3=saccharides

• 4=nucleotides

Amino acids in a protein are produced according to which

biomolecule?

• Lipids

• Enzymes

• DNA

• Carbohydrates

This biomolecule is composed of three basic elements; carbon, hydrogen, and oxygen. Each of these elements are arranged in a 1:2:1 ratio and are arranged in long polymers called starches. A starch is composed of many monomers of glucose, fructose, or galactose. Stored starches are different in plants and animals. Plants

have a starch called cellulose. Animals have a starch called glycogen. What is this biomolecule?

• Carbohydrate

• Protein

• Lipid

• Nucleic acid

This biomolecule is composed of three basic elements: carbon, hydrogen, and oxygen. This biomolecule can be found in the form of unsaturated or saturated fats. Unsaturated fats will have double bonds between some carbon atoms, and saturated fats contain single bonds between all carbon atoms. This biomolecule is composed of monomers of fatty acids and glycerol. What is this biomolecule?

• Carbohydrate

• Protein

• Lipid

• Nucleic acid

Glucose (C6H12O6) is used by organisms to obtain energy. What type of biomolecule is glucose?

• Carbohydrate

• Nucleic acid

• Protein

• Lipid

This biomolecule is composed of five basic elements: carbon, hydrogen, oxygen, nitrogen, and sulfur. Sulfur is unique to this biomolecule. These are composed of smaller monomers of amino acids that are bonded together by peptide bonds to form a polypeptide chain. What is this biomolecule?

• Carbohydrate

• Protein

• Lipid

• Nucleic acid

How do enzymes affect the rate of a reaction?

• Decrease it

• Increase it

• Keep it stable

• They have no effect

Animal and Plant Cells are...

• Shopkoytes

• Eukaryotes

• Prokaryotes

• The building blocks of non-living things

What is the smallest LIVING unit of LIVING THINGS?

• a cell

• a mitochondria

• a brick

• a protein
