Document Summary
Survival of the fittest: evolution, natural selection, speciation, adaptive radiation. Adapt to situations around them and the species pass on genes. Gradual: convergent evolution, exotoxin, endotoxins, bacterial shapes. Spinelli: bonds: attraction molecules have toward each other. Iconic: electron transferred from one substance to the other (salt) Hydrogen: unequal sharing of electrons (water) polar covalent bond: dehydration, hydrolysis, macromolecules. Enzyme: a protein that speeds up the chemical reaction by lowering the energy of activation (teacher assistant) Substrate: the substance which the enzymes acts on. Lock and key arrangement is an example of the enzyme and substrate relationship: exergonic, endergonic, plasma membrane, types of transport. Gate keeper as it allows certain things to come in and certain to leave with semipermeable membrane. Active transport: using energy to swim across the current: lower concentration to higher concentration. Passive transport: no energy is needed equalize pressure inside and outside: higher concentration to lower concentration, cellular respiration.
