Biomolecules
2
Carbohydrates Elements: C, H, O Monomer: mono- saccharides Polymer: polysaccharides Glucose
3
Carbohydrates Function: –Energy storage –Identification on surface of cell membrane Glucose
4
Lipids Elements: C, H, some O Subunits: glycerol + fatty acids Phospholipid
5
Lipids Function: –Long term energy storage –Main part of cell membrane hydrophobic Phospholipid
6
Proteins Elements: C, H, O, N Monomer: amino acids Polymer: polypeptide (protein)
7
Proteins Function: –Make reactions and cell processes happen –Build bones and muscle –fight disease
8
Nucleic Acids Elements: C, H, O, N, P Monomer: nucleotides Polymer: DNA or RNA Pyrimidines (DNA)Purines (DNA) Nucleotides
9
Nucleic Acids Function: 1. Carry genetic info Pyrimidines (DNA)Purines (DNA) Nucleotides
10
Macromolecules include that consist of which contain that consist of which contain CarbohydratesLipidsNucleic acidsProteins Sugars and starches Fats and oils Carbon, hydrogen, oxygen Carbon, hydrogen, oxygen Carbon,hydrogen, oxygen, nitrogen, phosphorus Carbon, hydrogen,oxygen, nitrogen DNA and RNA NucleotidesAmino Acids Glycerol and Fatty Acids Monosaccharides Collagen, Keratin
11
Cell Membrane Structure Extra cellular Fluid Cytoplasm
12
Cell Membrane Structure Proteins Add stability and some have carbohydrates attached
13
Cell Membrane Structure Carbohydrates Act as chemical ID tags
14
Cell Membrane Structure Protein channel Allow larger or charged molecules to pass through the membrane by facilitated diffusion.
15
Cell Membrane Structure Phospholipids Flexible, yet strong barrier of the cell; is semipermeable.
16
Cell Membrane Structure Hydrophilic head Hydrophobic tail
17
Macromolecule reteach Explain which biomolecule is represented… There may be more than one…
18
Contains Carbon Carbohydrate Protein Lipid Nucleic Acid
19
Contains Carbon, Hydrogen, and Oxygen, Nitrogen, Phosphorus Nucleic Acid
20
Contains Carbon, Hydrogen, and Oxygen Carbohydrate Protein Lipid Nucleic Acid
21
Contains Carbon, Hydrogen, and Oxygen, Nitrogen Protein Nucleic Acid
22
The main part of the cell membrane (yellow in the diagram) Lipid
23
The passageways through the cell membrane (pink in the diagram) Protein
24
The “identification tags” the cell membrane (blue in the diagram) Carbohydrate
25
A long string of Amino Acids Protein
26
Function is to make up the cell membrane that won’t dissolve in water Lipids
27
A polysaccharide Carbohydrate Monosaccharide
28
DNA Nucleic Acid
29
Function is to carry genetic information Nucleic acids
30
Large, complex folding chain of amino acids Protein Amino acids
31
Function is for energy storage and usage Lipid and Carbohydrate
32
A dissaccharide Carbohydrate Monosaccharide
33
Monomer: nucleotide Nucleic Acid Nucleotide Key Adenine (A) Thymine (T) Cytosine (C) Guanine (G)
34
Function is to build bones and muscle Proteins
35
Phospholipids Lipid
36
Hemoglobin transports oxygen in our blood. Protein
37
Function is to control cell functions Protein
