Document Summary
Debate in the early 20th century: golgi the nervous system is composed of a network of interconnected fibers: a (cid:862)(cid:374)e(cid:396)ve (cid:374)et(cid:863, cajal neuron hypothesis. Neural connections: the appearance of each neuron tells us something about the connections that it must make. Input, output information: motor neurons, are distinctively large and pass information on to command muscles to move. Dna is comprised with four different types of nucleotides: adenine (a), These nucleotides can be grouped into different pairs. A p(cid:396)otei(cid:374)"s shape a(cid:374)d its a(cid:271)ility to (cid:272)ha(cid:374)ge shape and to combine with other proteins are central to its function. Four levels of protein structure: whether a polypeptide chain forms a pleated sheet or a helix and its ultimate three-dimensional shape are both determined by the sequence of amino acids in the primary structure. Sequence of chains of amino acid in tertiary structure. Protein has a receptor site for glucose: glucose molecule enters protein. Protein changes shape when glucose docks with the receptor.
