Cells Flashcards
Macromolecules
A big molecule in a biosphere.
Type of molecule that make up living things.
Protein, carbohydrates, nucleic acid
Lipids (not polymer)
Polymer
Molecule made of small repeating units
Ex protein, carbohydrates & nucleic acid
Monomer
The small unit that is repeated in a polymer
Carbohydrates
Kolhydrat
Made up of polysaccharides (made of monosaccharides) .
Stores energy
Used to build cell wall
Necessary for cellular respiration - make atp
Monosaccharide
The Simplest form of sugars and the most basic units (monomers) from which all carbohydrates are built.
Ex glucose
Polysaccharides
Many monosaccharides
Ex glycogen
Kedjda av sammanbundna socker molekyler
Monomeric unit
The repeating unit/monomer
Ex monosaccharides are the monomeric unit of polysaccharides
Protein
Made of amino acids.
True polymer
Protein structure lvls
1. Primary: offer of amino acids
2. Secondary: amino acids folding into a repeating pattern
3. Tertiary: amino acid chain folded into new shapes. (3D)
R quarternary: (opt) protein consisting of more than 1 chain.
Amino acid
20 unique acids
Kemisk förening som innehåller en amino grupp & en karboxylgrupp
DNA
Stores genetic instructions for protein synthesis and reproduction.
A nucleic acid.
Made of nucleotides.
In eukaryotes: bound around proteins in nucleus.
In prokaryotes: ringformad. Inte i nucleus.
RNA
Nucleic acid.
Made of nucleotides.
Macromolecule
1 sträng, har U istf T
Nucleic acid
Dna o rna
Made from nucleotides.
2 types:
pyrimidines: 5 + 6 member ring nitrogenous base
purines: 6 member ring nitrogenous base.
Lipid
Not a true polymer, has sections that are polymer like.
Head= hydrofile, tail= hydrophobic (polymer part), have polar atoms
➡️allows only specific things through
Stores energy, insulates, cellmembrane, Messenger molecules, carry/ catch molecules/atoms.
Organelle
Organ like structures with specific instructions.
i ett eget membran
Finns i eukaryotes. Prokaryotes lack the majority of organelles
Ribosome
Site of protein synthesis from dna instructions. Made up of rna and proteins. Has 2 subunits: large ru. and small ru. In Large ru there are 3 tRNA binding locations; A, P & E
