BIO_SC 1010 Lecture Notes - Lecture 33: Citric Acid Cycle, Cellular Respiration, Pyruvic Acid
Document Summary
Emphasis on questions a lot of people missed. Takes carbon dioxide out of atmosphere, pulls it back into living things. To maintain carbon levels, need sources = sinks. Deer, birds, fish, ferns, water lilies, insects, bacteria, fungi, algae. Community: how all living things in an area interact. Ecosystem: how all species in area interact with surround environment (all biotic & abiotic) Photosynthesis: co2 + h20 -----> c6h12o6 + 02. Cellular respiration: c6h12o6 + o2 ------> co2 + h2o + energy (stored in. Glycolysis breaks down glucose into pyruvate (takes place in cytoplasm) Strips pyruvate of electrons, electrons picked up by nad+ Electrons used by electron transport chain to build h. Potential energy from h powers formation of atp. Silent mutation a change in the dna does not change the amino acid coded for. Missense mutation a change in the dna causes a different amino acid to be coded for.
