CELLULAR RESPIRATION -is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP)‚ and then release waste products. The reactions involved in respiration are catabolic reactions‚ which break large molecules into smaller ones‚ releasing energy in the process as weak so-called "high-energy" bonds are replaced by stronger bonds in the products. Respiration is one of the key ways

Cellular Respiration is part of the metabolism of organisms‚ it provides the energy for organisms’ basic life activity. The process of cellular respiration converts oxygen and water to glucose and carbon dioxide‚ and usually occurs inside of mitochondria. Thus the cellular respiration is closely related to the life of all organisms‚ especially the human. In a case study in cellular respiration‚ seven unrelated people died in five days‚ and the reason is unclear. However‚ all the victim had same

Biology 11 December 12 ‚ 2012 Photosynthesis and global warming Introduction: Photosynthesis can reduce the amount of carbon dioxide in the air. It represents a sink for carbon dioxide in the environment. Reducing forests and other vegetation can produce a net increase in atmospheric carbon dioxide. Therefore‚ more photosynthesis might act to reduce global warming. On the other hand‚ this is a more complicated title than it appears at first. Photosynthesis: The process in green plants

is called photosynthesis. This process is used by plants and other organisms for synthesis of lipids and amino acids or can be metabolized during cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon

explain to you why photosynthesis is bad while helping Earth too. I will be giving you a few reasons to explain that photosynthesis is important. So even though photosynthesis can kill the plant‚ photosynthesis is important‚ because it helps grow food for omnivores and herbivores. Photosynthesis grows plants and trees‚ which produce clean‚ fresh oxygen. Photosynthesis helps us living organisms with lungs breathe. It helps us when plants go through the process called photosynthesis. During this process

Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However‚ after reaching an intensity of 10‚000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may‚ in fact‚ slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100‚000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed

and NAD+ is finite (limited). What happens to cellular respiration when all of the cell’s NAD+ has been converted to NADH? If NAD is unavailable‚ the cell is unable to conduct any processes that involve the conversion of NAD+ to NADH. Because both glycolysis and the Krebs cycle produce NADH‚ both of these processes shut down when there is no available NAD+. 5. If the Krebs cycle does not require oxygen‚ why does cellular respiration stop after glycolysis when no oxygen is present? When no

Cellular Respiration Purpose The purpose of this experiment was to determine the effect of body mass and temperature on the rate of respiration in the mouse. Hypothesis When the temperature is reduced‚ cellular respiration will increase. Measurement Weight the mouse and use soda lime for mouse to perspire. Oxygen was inhaled and carbon dioxide was exhaled. Carbon dioxide was absorbed by soda lime. Rate of respiration was measured in terms of ml of oxygen per min over grams. General
