Associate Program Material – Heather Earnhardt Cell Energy Worksheet Answer the following questions: Cellular respiration: What is cellular respiration and what are its three stages? Cellular respiration is the process by which electrons are transferred between glucose to coenzymes and then to oxygen. NTP is made by the relocation of electrons. The end result of the process is the carbon dioxide and water that are released as byproducts of the process. The three

colored because of their absorption of light within regions of the visible spectrum. The color of light we can see is composed of the wavelengths that the object did not absorb. Photosynthesis in plants takes place in organelles called chloroplasts. Chloroplasts contain a number of coloured compounds‚ known as pigments‚ in their thylakoids‚ where light dependent reactions occur(Mitchelsl‚ Reece). Spinach leaves contain chlorophyll a and b and b -carotene as major pigments as well as smaller amounts

the photosynthetic qualities using a spectrometer at 605nm. Photosynthesis is the process by which the suns visible light (electromagnetic radiation) is utilised by organisms with photosynthetic abilities (pigments called chloroplasts) as a chemical energy source. Living chloroplasts can be readily isolated from live plant tissue and used to investigate photosynthesis (Lilley et al. 1975; Halliwell 1984). Photosynthetic organelles are Eukaryotic and are fundamental for the survival of not only the organisms

They also use energy from light. However‚ not all organisms that use light as a source of energy carry out photosynthesis. Chloroplasts are necessary for photosynthesis to take place‚ and they specifically use chlorophyll‚ the green pigment involved in photosynthesis. Because of this‚ photosynthesis most often takes place in the leaves of plants‚ since that is where the chloroplasts can be found. Since photosynthesis requires carbon dioxide‚ water‚ and sunlight‚ all of these substances must be obtained

it able to absorb more sunlight. The leaves and all of the green parts of the plant’s top layer are made of a specially adapted cell. These cells have a very thin cell wall so sunlight can penetrate it easily. After this‚ the sunlight reaches chloroplasts which are plastids containing chlorophyll. This is where photosynthesis actually takes

high energy state in the form of NADPH. This process is also coupled with ATP synthesis. The photosynthetic electron transport occurs in thylakoid membranes inside chloroplasts. It was first demonstrated by Robert Hill that photosynthesis could be “uncoupled” if the thylakoid membranes and the stroma components of chloroplast are separated via cell fractionation. The Hill reaction is also referred to as photolysis of water with the subsequent evolution of oxygen. Isolated thylakoids do not
