Photosynthesis is broken down into two separate stages, the light-dependent reactions and light-independent reactions. In the light-dependent reaction, the chloroplast traps light energy from the sun and it is converted into ATP and NADPH energy. In the light-independent reaction, NADPH delivers the hydrogen and carbon dioxide atoms that help form glucose, and ATP donates energy to areas where glucose is put together from carbon. This process occurs in chlorophyll bearing cells. Chlorophyll is an amazing chemical that is the essential ingredient in photosynthesis.

The metabolic reactions take place in the mitochondria of the cells of an organism. On the other hand, photosynthesis is a chemical process that happens in the presence of sunlight to enable plants manufacture their food and make stores of energy. The whole process happens within chlorophyll containing plants. Photosynthesis: H2O + Light Energy + CO2 ---> O2 + Carbohydrate (glucose) Respiration: Carbohydrate + O2 ---> H2O + ATP + CO2 (Wessels, 1) Biological Implication The biological implication of cellular respiration is production of energy from the food produced as result of photosynthesis. Therefore the implication of photosynthesis is
The role of the of the electron transport system is to turn the electrons given off from the other two processes and turn them into ATP. This process makes the most ATP in relation to the previous processes. This all happens within the mitochondria. Photosynthesis: • What is the overall goal of photosynthesis? To turn light into energy.
Photosynthesis is the process where light energy is converted into chemical energy in the form of glucose. Its overall equation is: 6CO2 + 6H20 + light energy C6H12O6 + 6O2. The process of photosynthesis can be split into two reactions: the light-dependent reaction in the thylakoids and the light-independent reaction in the stroma. During the light-dependent reaction, light energy from the Sun is absorbed by chlorophyll (found in the chloroplasts in the leaf). This causes the excitation of two electrons, and they move to a higher energy level.
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.
Purpose To demonstrate that CO2 is used during photosynthesis. To demonstrate that CO2 is produced during cellular respiration. III. Hypothesis 1. If we put elodea, bromthymol blue, seltzer water, and regular water in a vial in the sunlight then we can demonstrate that carbon dioxide is used during photosynthesis because the indicator will turn blue.
Photosynthesis: - Outline what photosynthesis is/why autotrophs do it - Describe how carbon dioxide is used in photosynthesis. As it is used in the light independent stage (LIS), you should focus on this, not the light dependent stage (LDS). Respiration: - Outline what respiration is/why organisms all have to do it - Describe how carbon dioxide is produced in respiration. As it is produced in the link reaction and the Krebs cycle, you should focus on this, not on glycolysis and the electron transfer chain. Exchange of carbon dioxide between an organism and its environment: - Pick a couple of contrasting organisms (e.g.
When red and blue wavelengths are absorbed by chlorophyll they excite the electrons to a high amount causing photosynthesis to occur faster and with better results. From doing this experiment we should expect for the leaf disks in the red cellophane syringes to rise to surface in a short amount of time, we should expect the same from the blue cellophane syringes (Gray 2013). Hypothesis: Because chlorophyll reflects green wavelengths, it is predicted that the green wavelengths will not be absorbed. Therefore, green will have the least amount of photosynthesis. However, red and blue wavelength are absorbed better by chlorophyll and will excite electrons to high amounts, making photosynthesis occur at a faster rate.
