Document Summary

Trees are mostly made of carbon need to extract from environment. Catabolic pathway break down food molecules create building blocks for synthesis. Complex organ system that evolved to extract oxygen and deliver oxygen to tissues. 3 phosphate group + pentose sugar + nitrogen containing base (adenine) 1 phosphate group released adp + inorganic phosphate group (contains a lot of energy) Energy is released used for activities like active transport, muscle contraction etc. *not expected to know processes (don"t need to know diagram on slide) mitochondria produces atp. Unzip strands from one another (done by enzymes) Dna polymerase looks at nucleotides and adds the opposite nucleotide (complementary bases) semiconservative take parent strand and create new strands. 3 sets of nucleotide bases that will encode for 1 amino acid = codon (sequence of bases) B/c code of 3, must know starting place.
