...ctron transport between photosystemII and plastoquinone. Plastoquinone is the first agent that shuttles electrons but DCMU stops it from receiving the electrons. Since plastoquinone does not receive the electrons the transport of electrons is slowed down and less ATP and NADPH are produced. NH4CL is acted as an uncoupler in the lab. Uncouplers destroy the proton gradient, and allow protons to pass freely bypassing ATPase. ATP production stops but electron transport continues. Since there is no gradient electrons move faster because there is less resistance due to ATP production being ceased. The information obtained from this lab is utilized in everyday life and we may not even n notice it. Uncoupling of NH4CL is the reason why animals dislike the smell of ammonia. It is also the reason NH4CL must be absorb quickly into amino acids when used as a plant fertilizer.

- The Effect of Light Intensity on the Rate of Photosynthesis Introduction Green plants don't exude food from the soil they make their own, using sunlight. This is called photosynthesis, which means "making through light". This occurs in the cells of a green plant, which are exposed to sunlight. Four things are needed to make this process work and this gives two thing: the four things needed are light from the sun, carbon dioxide diffuses from the air, water from the soil and chlorophyll in the leaves....

- The Effect of Light Intensity on the Rate of Photosynthesis Plan: Aim: To investigate the affect of light intensity on the rate of photosynthesis. Theory: Before I predict what will happen I must look at how photosynthesis occurs. Photosynthesis is the way plants create a source of food for themselves. Photosynthesis requires the following resources; Carbon Dioxide, Water and light. Inside the leaves of a plant there is a green substance, this substance is known as chlorophyll.... [tags: Papers]

- A study using an O2 electrode to measure the amount of O2 produced or consumed over an amount of time with varying light intensities to determine the effect of light intensity, CO2 and Diuron on the rate of photosynthesis of Spinacia oleracea. Introduction Photosynthesis is the process in which chloroplasts found in plants, algae and some bacteria are used to convert light energy to chemical food energy. (Reece, et al. 2012, p. 190) (Molecules, Genes & Cells Laboratory Manual 2016). Photosynthesis can be broken down into two parts, light dependent reactions and light independent reactions or Calvin Cycle.... [tags: Photosynthesis, Calvin cycle, Oxygen]

- Investigating the effects of light intensity, NH4CL, and DCMU on the rate of electron transport in spinach thylakoid membranes was the purpose of this lab. Photosynthesis is the process that routinely drives electron transport across the thylakoid membrane but can be impacted when additional factors are added. Two phases known as Light reactions and the Calvin cycle makeup photosynthesis. Plastoquinone shuttle, water oxidation, and NADP+ reduction are the major factors of the light reactions. Photosynthesis creates a proton gradient when pigments in the thylakoid membrane absorbs light energy from the sun.... [tags: Photosynthesis, Cellular respiration]

- The Effect of Light Intensity and Temperature on the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. To do this, I will place a piece of pondweed in varying light intensities and temperatures, and observe the amount of oxygen being given off. I am using pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water. Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells.... [tags: Papers]

- The Effect of Light Intensity on the Rate of Photosynthesis in an Aquatic Plant Introduction The input variable I will be investigating is light, as light is just one of the 4 factors required in the green-plant process of photosynthesis. Photosynthesis is the process by which green-plants use sunlight, carbon dioxide, water & chlorophyll to produce their own food source. This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes... [tags: Papers]

- An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis Introduction Photosynthetic takes place in the chloroplasts of green plant cells; it can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [IMAGE]6CO2 + 6H20 C6 H12 O6 + 6O2 it has been proven many times that plants need light to be able to photosynthesize , so you can say that without light the plant would neither photosynthesize or survive....

- Lab Report Testing the Effect of Light Intensity on the Rate of Photosynthisis I'm going to investigate the amount of light used in photosynthisis to see if it has a noticable effect when you increase or decrease the light intensity. Photosynthisis is the way in which light and carbon-dioxide is used by a plant to produce energy in the form of starch. 6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....

An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea
- An Investigation into the Effect of Light Intensity on the Rate of Photosynthesis on a Piece of Elodea Plan: Method: 1) First I will put some water into a boiling tube and add 5 spatulas of Sodium Hydrogen Carbonate. I will add 5 spatulas of Sodium Hydrogen Carbonate as it reacts with water and forms carbon dioxide; also I have so much so that I have carbon dioxide in excess. 2) Then I will cut off 5cm of elodea and place it into the boiling tube. 3) Thirdly I will place the boiling tube in a test tube holder 5cm in front of the light source....

The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place
- The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place Hypothesis: I predict that as the intensity of light is increased, so would the photosynthesis. Furthermore, I predict that if the light intensity increases, the rate of photosynthesis will increase at a proportional rate and more oxygen will be produced and therefore the oxygen levels will increase. However, the lower the light intensity, less oxygen will be produced which would affect this investigation.... [tags: Papers]
