1. Explain the distinction between the cytosol and the cytoplasm of a cell? Tell whether lysosomes, mitochondria, ribosomes and DNA are part of the cytosol or the cytoplasm or both. Do bacteria have a cytosol or a cytoplasm?
4. Describe the chemistry of carbon atoms. Tell about their electron configuration and their capacity to form covalent bonds including double bonds. Also, explain how carbon-based molecules can be so large and heavily branched.
6. To the FOUR carbon molecule below, add each of the following functional groups: sulfhydryl, aldehyde, phosphate and amino. Make sure you have enough hydrogen atoms. C â C â C â C
7. Mutations that cause changes in protein sequence can alter or eliminate the function of that protein. Would you expect a mutation that changed a valine to a leucine to have MORE or LESS of an effect on the protein function than a mutation that changed valine to asparagine? Explain your answer.
