SHS - Macromolcules, Carbohydrates, Lipids, Proteins

Monosaccharides are monomers of

1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids 1 is the correct answer because Glycerol and fatty acids are the building blocks for lipids, nucleotides are the building blocks for nucleic acids and amino acids are the monomers of proteins

Waxes, oils and fats are examples of

1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids 2 is the correct answer because these are all insoluble in water

Nucleotides are monomers of

1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids 4 is the correct answer because Glycerol and fatty acids are the building blocks for lipids, monosaccharides are the building blocks of sugar/carbohydrates and amino acids are the monomers of proteins

DNA and RNA are examples of

1. Carbohydrates 2. Lipids 3. Proteins 4. Nucleic Acids 4 is the correct answer because they are nucleotides which are the building blocks of nucleic acids

Which factor denatures a enzyme?

1. Excessive heat 2. Nothing can 3 Exposure to light 4. Exposure to bacteria 1 is the correct answer because an enzyme can only be denatured by high temperature or extreme pH

Proteins are made of monomers called ___________

1. Nucleotides 2. Monosaccharides 3. Amino Acids 4. Glycerol and fatty acids 3 is the correct answer because Glycerol and fatty acids are the building blocks for lipids, monosaccharides are the building blocks of sugar and nucleotides are the building blocks for nucleic acids

I am responsible for long term energy storage in mammals.

1. Protein 2. Lipid 3. Carbohydrate 4. Nucleic Acid 2 is the correct answer because proteins regulate tissues and organs, carbohydrates give energy and nucleic acids hold genetic information

Important to the structural integrity of plant cells, this is the single most popular polysaccharide in the world.

1. Starch 2. Glycogen 3. Cellulose 4. Chitin 3 is the correct answer because it makes up plants' cell wall and is the only polysacchride

Which is a carbohydrate's monomer?

1. Sugar 2. Amino acids 3. Monosaccharide 4. Nucleotide 3 is the correct answer because sugar is a carbohydrate and amino acids make up proteins and nucleotides make up nucleic acids

The "lock and key hypothesis" attempts to explain the mechanism of?

1. Vacuole formation 2. Pinocytosis 3. Sharing of electrons 4. Enzyme are specific to a substrate 4 is the correct answer because the model shows that enzymes only work with certain substrates

Which of the following contains the genetic code for protein synthesis?

1. carbohydrate 2. lipid 3. protein 4. nucleic acid 4 is the correct answer because DNA and RNA is a type of nucleic acid

Which of the following organic compounds is the main source of energy for living things?

1. carbohydrates 2. lipids 3. nucleic acids 4. proteins 1 is the correct answer because carbohydrates are used as sources of energy

All organic compounds contain the element

1. carbon 2. nitrogen 3. phosphorus 4. sulfur 1 is the correct answer because organic compounds must have carbon because it can form many types of covalent bonds

Which is an example of a lipid

1. fat 2. starch 3. glucose 4. hemoglobin 1 is the correct answer because starch and glucose are carbs and hemoglobin is a protein

Which subunits make up the structure of all proteins?

1. glucose 2. amino acids 3. carbohydrates 4. fatty acids 2 is the correct answer because glucose makes up carbs and fatty acids make up lipids

What are the monomers of DNA?

1. glycerols 2. amino acids 3. fatty acids 4. nucleotides 4 is the correct answer because glycerol and fatty acids make up lipids and amino acids make up proteins and both nucleotides and DNA make up nucleic acids

Enzymes belong to which class of macromolecules?

1. lipids 2. carbohydrates 3. proteins 4. nucleic acids 3 is the correct answer because enzymes are a type of amino acids which are the building blocks of proteins

Which macromolecule stores energy, insulates us, and makes up the cell membrane?

1. lipids 2. proteins 3. carbohydrates 4. nucleic acids 1 is the correct answer because nucleic acids hold genetic information, the carbohydrate provides energy, and proteins regulate the body's tissue and organs

All polymers are made up of...

1. monosaccharides 2. monomers 3. proteins 4. None of these 2 is the correct answer because proteins and monosaccharides are a type of polymers

Lipids can be digested into what smaller subunits?

1. nucleic acids 2. amino acids 3. fatty acids 4. glucose 3 is the correct answer because nucleic acids digest into nucleotides, amino acids make up proteins and glucose are a type of carbohydrates

Sugar belongs to which class of macromolecules?

1. proteins 2. lipids 3. nucleic acids 4. carbohydrates 4 is the correct answer because the building blocks of carbohydrates are monosaccharides which are simple sugars

DNA belongs to which class of macromolecules?

1. proteins 2. nucleic acids 3. carbohydrates 4. lipids 2 is the correct answer because DNA is a nucleotide which are the building blocks of nucleic acids

What is the function of nucleic acids?

1. store genetic information 2. store energy (long-term) 3. store energy (short-term) 4. build skin, hair, nails, muscles 1 is the correct answer because of RNA and DNA (which store genetic information) are examples of nucleic acids

Which is NOT a monomer?

1. sucrose 2. glucose 3. amino acid 4. fatty acid 1 is the correct answer because the rest have a carboxyl group which monomers don't have

The word saccharide means:

1. sugar 2. glucose 3. sweetener 4. carbohydrate 1 is the correct answer because monosaccharide is a simple sugar
