Answers to Photosynthesis Practice AP Biology 1. Draw a picture of the chloroplast and label the stroma‚ thylakoid‚ thylakoid lumen (space)‚ inner membrane‚ outer membrane. 2. Using 18O as the basis of your discussion‚ explain how we know that the oxygen released in photosynthesis comes from water. When the oxygen in water has the radioactively labeled oxygen‚ the gas released from photosynthesis also has the labeled oxygen. This shows that the oxygen gas given off during photosynthesis comes from

Photosynthesis depends on an interaction between two sets of reactions: the light reactions and the Calvin cycle. Chlorophyll and the other molecules responsible for the light reactions are built into the thylakoid membranes. The enzymes that catalyze the Calvin cycle are located in the stroma. Beginning with the absorption of light by chlorophyll‚ the light reactions convert light energy into chemical energy in the form of ATP and NADPH. The ATP provides the energy‚ and the NADPH supplies the electrons

THE RELATIONSHIP OF ELECTRIC FIELD INTENSITY AND ITS DISTANCE FROM THE CHARGED OPOINT PHYS-232 JIANSONG HE GROUP: Abstract This experiment was performed to find the electric field strength from different distance to the charged point. The field strength was determined statically‚ by measuring its electrical potential when subjected to loading‚ and dynamically‚ by measuring the electrical potential at different location on the conductive paper. The electrical potential was measured from three

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

If you drink different beverages before exercising‚ then you will do better with Gatorade. In this experiment‚ the independent variables are the different types of beverages that will be used. The dependant variables (the variables influenced by the different beverages) is the running time (the time that the person will run in one lap)‚ the amount of pushups

animal tissues. Its purpose is to destroy toxic substances which may be introduced into cells. Also‚ some cells use catalase to destroy cellular debris or worn out organelles. In this lab‚ we will use a catalase solution from potatoes and determine the effect of temperature and pH on the action of this enzyme. The substrate of the enzyme will be 3% hydrogen peroxide (H2O2). Catalase works by the following mechanism: 2 H2O2 ------------------>____2 H2O+ O2 Materials: • 1M HCl • 6 test tubes

10 June 2012 Abstract: In this experiment‚ 8 plants will be tested. Each except one plant (which will be the control group) will receive a certain amount of water starting at 0 teaspoons of water. Each plant will receive 1 more teaspoon than the previous cup‚ so it would be increasing. For example‚ cup 4 will have 4 teaspoons of water and cup 3 would have 3. The data recorded will be the length the plant grows up to. Goal: The goal in this experiment is to see what amount of water grows

w The Effect of Changing the surface area on the Rate of Reaction? By : 22/10/2013 The effect of changing the surface area on the rate of reaction? Unit Question: Should we speed things up or slow them down? Hypothesis: According to collision theory‚ should the surface area increase the amount of collisions increase increasing the rate of reaction. Therefore‚ my hypothesis is that when the surface area

These factors include the effect of blood vessel radius‚ the effect of blood viscosity‚ as well as the effect of blood vessel length‚ and the effect of blood pressure. This better understanding of cardiovascular dynamics was achieved with PhysioEx 9.1. Hypothesis: Hypothesis- Activity 1: Studying the Effect of Blood Vessel Radius on Blood Flow
