Basicity rules correct answers -strong base: unstable/reactive (ED groups) -weak base: stable (EW groups/more EN/bigger) Chair conformation correct answers -more stable equitorial (slanted) -pointing up/pointing down=cis if both up -elimination: trans and diaxial Newman projection correct answers -gauche: substituent groups adjacent to eachother -grab middle and turn to put in plane Enantiomers correct answers -not superimposable mirror images -same besides stereochemistry Diast...

Peroxisomes are so named because they usually contain enzymes that use oxygen to remove hydrogen atoms from specific substrates in an oxidative reaction that produces H2O2, which is a powerful oxidant and potentially destructive if it accumulates or escapes from peroxisomes. Ribosomes are RNA-protein complexes (nucleoproteins) that are synthesized in the nucleolus and secreted into the cytoplasm through pores in the nuclear envelope called nuclear pore complexes. Lysosomes are saclike s...
