thereby‚ able to be used to do photosynthesis. The green light we can see is not/cannot be absorbed by the plant‚ and thus cannot be used to do photosynthesis. The overall chemical reaction involved in photosynthesis is: 6CO2 + 6H2O (+ light energy) C6H12O6 + 6O2. This is the source of the O2 we breathe‚ and thus‚ a significant factor in the concerns

Conclusions The amount of cellular respiration increases based on the amount of exercise. The equation for cellular respiration is C6H12O6 + 6O2 ⇒ 6CO2 + 6H2O + ATP. Glucose is broken down into 2 pyruvate. The pyruvate then travels through the Kreb cycle and produces carbon dioxide. The oxygen travel through the electron transport train and produces water and energy. In order for the body to maintain homeostasis while exercising more oxygen is needed and cellular respiration increases. In return

The Fermentation and Distillation of Alcohol By Bhanupriya Chettiar 301 Group Members: Bhanupriya Chettiar‚ Rachel Min‚ Zoe Chandler‚ Bianca Main Aim The aim of the practical is to prepare ethanol by fermentation and to isolate it by fractional distillation. Introduction This practical’s aim is to prepare ethanol using two steps; fermentation and then fractional distillation. Many alcoholic drinks for example‚ brandy and whisky‚ are prepared using this method but to a larger scale. The first
