Document Summary
Methane tunnels present at the bottom of the sea and it has been thought to be a good energy source, if a method to mine them is created: downside: found that high pockets of methane can explode, and the effects of that on the atmosphere is currently unknown. Rna helps produce polypeptides; structure and catalytic function: lipids (diverse structures): structure; make up the physical boundary between the inside of the cell and surroundings + internal organelles, polysaccharides (sugar): structural (cellulose) and energy storage (glycogen and starch, rna polymersase (cytoplasm): produce rna from dna templates, gylcogen phosphorylase (cytoplasm): conversion of glycogen to glucose monomers, na+/k+ atpase (plasma membrane): active transport of na+ and k+ across the membrane, from areas of high [ ] to low [ , flagellin (bacterial flagellum): aid in bacterial motilitiy, ftsz (associated with plasma membrane of bacteria): component of cell division machinery.
