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 model was that the atoms were tiny, indivisible, indestructible particles and that each one had a certain mass, size, and chemical behavior that was determined by what kind of element they were. We will use that model of an atom for now, but we will modify it considerably in a later lesson. Top of Page.
