Without vitamin B1 (thiamine) the cycle would slow causing decreased energy production. Thiamine is also important in the production of NADPH via the pentose phosphate pathway. NADPH plays a crucial role in biochemistry because it donates its electron pairs to numerous anabolic reactions.
John Dalton - 1808 John Dalton created the very first atomic theory. Dalton viewed atoms as tiny, solid balls. Dalton was an English school teacher who performed many experiments on atoms. His atomic theory had 4 statementsâ¦
Dalton's Atomic Theory Democritus first suggested the existence of the atom but it took almost two millennia before the atom was placed on a solid foothold as a fundamental chemical object by John Dalton (1766-1844).Although two centuries old, Dalton's atomic theory remains valid in modern chemical thought.) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms. Modern atomic theory is, of course, a little more involved than Dalton's theory but the essence of Dalton's theory remains valid.
