What does organic chemistry study? Focuses on the chemical and physical properties of carbon compounds What does inorganic chemistry study? The field dealing with metals, minerals, and other non-organic compounds How many bonds can a Carbon form? 4! Due to having 4 valence electrons What is a long chain of carbons called? Polymers What is a cyclic compound? Carbons joined together in a closed chain
What are carbon compounds called? Alkanes Condensed structures give a better idea of a molecules structure, compared to chemical formula. T or F T Structural formula gives an even better idea of a molecules structure, compared to chemical formula T Advantage of cyclic carbon compounds They are more restricted in their movements and orientation - advantageous for building structures and maintaining shape Carbon can form double and triple bonds with other carbon atoms or atoms of other elements. T or F T
Molecular mass of a Macromolecule 5,000 g/mol or greater What are daltons used for? Larger molecules use Daltons for mass. 1 Da = 1 g/mol Larger molecules develop more complex structures. T or F T What is 25,000 Da in Kilodaltons 25 kDa Monomers Single, smallest building block used to build macromolecules. What is the monomer of DNA? Of proteins? Of carbohydrates? Nucleotide; Amino Acids; Sugar molecule
Supramolecular Complexes A complex of two or more macromolecules that routinely interact to function in the cell What is the purpose of a supramolecular complex? The macromolecules retain individual units but stick to one another for a time to accomplish a task and then often break apart once the job is done. All cells are defined by a _____ Plasma membrane (or cellular membrane) What is the plasma membrane made of? Lipids and non-polar proteins, making it impermeable to water, ions, and large molecules. Prokaryotes vs. Eukaryotes Prokaryotes include bacteria and other single celled organisms. Eukaryotes are the larger multicellular organisms that include algae, fungi, plants, and animals. Main difference between Eukaryotes and Prokaryotes.
What do Biochemists study?
- The relationship between structure and function of biomolecules
- Chemical reactions of organisms
- Communication within and among organisms Smaller elements are favored because they can form stable covalent bonds. T or F True. Strong bonds form by significant overlap of atoms, such as carbon and hydrogen, allowing them to share electrons. What is the bond angle of a Linear molecule? 180 degrees What is the bond angle of a Trigonal Planar? 120 degrees What is the bond angle of a Trigonal Pyramidal? 107.5 degrees
what is the bond angle of Tetrahedral? 109.5 degrees What is carbon referred to in the chemical world? The superglue What organelles have a function of breaking down? Peroxisome, Lysosome or vacuole What produces energy? Chloroplasts and Mitochondria Double Membrane (in Eukaryotes) separate from the rest of a cell. Nucleus (in Eukaryotes)
Cellular Respiration Produces ATP Nucleiod (In prokaryotes) localized area, not separate from cytoplasm. Takes up about 20% of cell volume. Contains the genome
