was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its location near the carbonyl on acetophenone. When the sodium hydroxide

BIOL2220 Lab 3: Hill Reaction Introduction In 1937‚ Robert Hill discovered that isolated chloroplasts can generate oxygen when they are illuminated in the presence of a suitable electron acceptor‚ even in the absence of carbon dioxide. This finding was a landmark in the study of photosynthesis because it established that the source of the electrons used in the light reactions is water. It also confirmed that the released oxygen is derived from water instead of carbon dioxide. In chloroplasts

When observing our individual‚ we observed that that the Jendrassik maneuver increased reaction time. We believe this is so because it acts as a distraction due to the individual concentrating on the maneuver. This tells us that even though simple reflexes don’t directly involve the brain‚ the brain does still have influence on simple reflexes. Reflexes can be an indication of nervous system health. When the reflexes are not acting properly or are absent‚ it can tell a physician if there may
