Cell Respiration & Photosynthesis BIO STUDY GUIDE (Ch. 9.1-9.5‚ 10.1-10.3) I) CELLULAR RESPIRATION A) Catabolic Pathways A.1) Fermentation: partial degradation of sugar that occurs w/o oxygen A.2) Cellular Respiration: oxygen is used A.3) Redox Reactions (Oxidation-Reduction that exchanges electrons) Oxidation: loss of electrons (energy must be added) Reduction: addition of electrons. (-) charged electrons added to atom reduce amount of (+) charge of that atom A.4) Stepwise Energy Harvest

vice versa. In a galvanic cell‚ the amperage is generated from flows of electrons between the two metals in the metal sulfate solution of the electrolyte. In order for a chemical reaction to take place‚ the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation

An investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions

Fermentation of Carbohydrates: Ethanol from Sucrose Objective: To demonstrate a fermentation process‚ isolate the ethanol produced by fractional distillation‚ determine the composition of the ethanol solution recovered‚ and make stoichiometric and yield calculations. Procedures: Fermentation Weigh out 20.0 g of sucrose and place it into a 250-mL Erlenmeyer flask. Add 100 mL of water and gently shake until all the sucrose has dissolved. To this solution add 0.60 g of dipotassium hydrogen phosphate

Product Description In our country‚ bread is the second most favorite food of the Filipinos‚ next to rice. Most of the Filipinos are used of having bread on their tables especially for breakfast and merienda. The classic example of an all-time favorite bread of the Filipinos is Pandesal. We also love other pastries such as doughnuts‚ cake‚ biscuits and the

Complex Carbohydrates PERSONAL SUMARY: There is a very real difference between simple and complex carbohydrates. Let’s look at them. Simple carbohydrates‚ found in rice‚ pasta‚ white potatoes‚ and some dairy products‚ contain sugars that are broken down quickly by your body. This will provide your body with a quick burst of energy‚ but if the carbohydrates are not used quickly‚ the sugar will turn to fat. That’s why low-carb diets cut them out. But those diets often lump all carbs together

1. How does a cell become differentiated? A cell becomes differentiated by using only the DNA that it needs. 2. Give an example of 2 differentiated cells. Two examples of differentiated cells are lysosomes and mitochondria. Lysosomes are small so they can move throughout the cell effectively. Mitochondria have a lot of surface area to make more energy 3. (Essay) What does it mean to be specialized? Explain how the structure of the cell determines its function. Give at least 3 examples. Being specialized
