Question

unit 1.1 biomolecules & cells test review
fill in the blanks with the correct biomolecule: protein, lipid, carbohydrate, nucleic acid
used by the body for long - term energy
contains carbon, hydrogen, oxygen, and nitrogen
two types are monosaccharides and disaccharides
used by the body for quick energy
contains carbon, hydrogen, oxygen, nitrogen, and phosphorus
used by the body for insulation.
an example is an enzyme.
tuna and other meats contain much of this.
pasta contains much of this.
stores information to make proteins in the form of a code.
the building block is an amino acid.
butter contains much of this.
used in the exoskeleton of insects.
helps transport oxygen in blood.
can be used in murder trials.
building block is a glycerol with three fatty acids
made of nucleotides
dna and rna are examples
supports immune functions
helps with waterproofing
the cell membrane is responsible for providing support to the cell and allows molecules to move in and out of the cell. what property of phospholipids helps to control what goes in and out?

Explanation:

1. Lipid is used for long - term energy storage in the body.
2. Protein contains carbon, hydrogen, oxygen, and nitrogen.
3. Carbohydrate has two types: monosaccharides and disaccharides and is used for quick energy.
4. Nucleic acid contains carbon, hydrogen, oxygen, nitrogen, and phosphorus.
5. Lipid is used for insulation in the body.
6. Protein (an enzyme is a type of protein).
7. Protein (tuna and other meats are high in protein).
8. Carbohydrate (pasta is a source of carbohydrates).
9. Nucleic acid (stores information for protein - making in the form of a code).
10. Protein (amino acids are the building blocks of proteins).
11. Lipid (butter is high in lipids).
12. Carbohydrate (chitin, a carbohydrate, is in insect exoskeletons).
13. Protein (hemoglobin in blood is a protein that transports oxygen).
14. Nucleic acid (DNA can be used in murder trials for forensic analysis).
15. Lipid (triglycerides have a glycerol with three fatty acids).
16. Nucleic acid (nucleotides are the building blocks of nucleic acids).
17. Nucleic acid (DNA and RNA are nucleic acids).
18. Protein (antibodies, a type of protein, support immune functions).
19. Lipid (lipids can help with waterproofing).

For the cell - membrane question, phospholipids have a hydrophilic head and a hydrophobic tail. The hydrophilic heads face the aqueous environments inside and outside the cell, while the hydrophobic tails face each other in the interior of the membrane. This property creates a semi - permeable barrier that controls what goes in and out.

Answer:

1. Lipid
2. Protein
3. Carbohydrate
4. Nucleic acid
5. Lipid
6. Protein
7. Protein
8. Carbohydrate
9. Nucleic acid
10. Protein
11. Lipid
12. Carbohydrate
13. Protein
14. Nucleic acid
15. Lipid
16. Nucleic acid
17. Nucleic acid
18. Protein
19. Lipid

For the cell - membrane question: The hydrophilic and hydrophobic nature of phospholipids creates a semi - permeable barrier.
