5 Matching Questions
- Golgi body
- a two sugar monomers.
- b an organelle of endomembrane system; enzymes inside its much-folded membrane modify new polypeptide chains and lipids; the products are sorted and packaged in vesicles for transport.
- c any separation of charge into distinct positive and negative regions
- d glucose chains stretched side by side and hydrogen-bonded to one another in a tightly bundled pattern, making it them able to resist hydrolysis by most enzymes. Cell walls in plants are made of these.
- e accepts hydrogen ions as it dissolves in water
5 Multiple Choice Questions
- in many cells (except animal cells), a semirigid permeable structure around the plasma membrane; helps a cell retain its shape and resist rupturing.
- an easily transported sugar made up of glucose molecules.
- a type of cell that starts life with a nucleus.
- any molecule of carbon, hydrogen, and oxygen, typically in a 1:2:1 ratio. Main kinds are monosaccharides, oligosaccharides, and polysaccharides.
- organelle of photosynthesis in plants and some protists.
5 True/False Questions
covalent bond → forms between two atoms with a small difference in electronegativity. In this type of bond, the 2 atoms do not share electrons equally. The more electronegative pulls the electrons a bit more towards it's direction -> slightly negative charge, other side = slightly positive
organelle → structure that carries out a specialized metabolic function inside a cell; e.g., a nucleus in eukaryotes.
electronegativity → the measure of an atom's ability to pull electrons from other atoms
hydrophilic → dissolves easily in water.
organic compounds → an organelle of endomembrane system; enzymes inside its much-folded membrane modify new polypeptide chains and lipids; the products are sorted and packaged in vesicles for transport.
