In experiment one‚ involving the rate of respiration of germinated peas when exposed to a variety of different temperatures. From a general standpoint the data collected matched the hypothesis formed‚ as the temperature increases the rate of respiration will increase as well. This was shown as the average ppm of oxygen was taken from each group. Comparing the data from the class is shows the effect of human error on the results. For example group #4 seemed to have back wards results this may

and energy as follows: C5 H12 O6 2C3 H6 O3 + energy Anaerobic respiration is a stage of cellular respiration that happens in the absence of oxygen. The first step is the breakdown of glucose in glycolysis. During this step glucose is broken down to two pyruvic acid molecules. The fate of pyruvic acid depends on whether there is oxygen available or not. In the absence of oxygen‚ pyruvic acid continues the anaerobic respiration pathway and is converted into lactic acid. Only six ATP molecules

loss of water vapour from the exposed parts of a plant; by evaporation from the leaves‚ stems and branches and by the escape of water vapour through the stomata. Respiration: Respiration is the breakdown of glucose molecules to synthesize(produce) energy.there are two types of respiration: aerobic respiration and anaerobic respiration. Consider the food chain below: Algae →larvae →crabs →fish (a)Name The producer; algae One carnivore; fish One herbivore; larvae The secondary consumer;

What is metabolism? All living things must have an unceasing supply of energy and matter. The transformation of this energy and matter within the body is called metabolism. Metabolism includes two different types: catabolism and anabolism. Catabolism is destructive metabolism. Typically‚ in catabolism‚ larger organic molecules are broken down into smaller constituents. This usually occurs with the release of energy. Anabolism is constructive metabolism. Typically‚ in anabolism‚ small precursor

Yeast is often used in bread dough to make the dough rise. With the presence of oxygen a yeast cell creates energy by performing cellular respiration and producing a high amount of ATP‚ but when in bread dough the absence

plants transform radiant solar energy into chemical energy that gets stored as potential energy in carbohydrates‚ and conduction of nerve impulses which is when chemical energy is transformed into electrical energy. An example of energy transfer is; respiration when the chemical energy stored in respiratory substrates is transferred to ADP and is stored in ATP. The ATP molecules transfer energy to other biological molecules. ATP‚ which stands for adenosine tri-phosphate‚ is an energy rich compound having

Role of a human circulatory system: Diffuse In – oxygen (O2)‚ dissolved food (glucose) and water (H2O) Diffuse Out – carbon dioxide (CO2)‚waste and water(H2O) Respiration – releasing energy in cells Breathing – getting air into and out of your body

Photosynthesis “deposits” energy‚ used carbon dioxide and water‚ and produces oxygen and glucose. By cellular contrast‚ cellular respiration “withdraws” energy‚ uses oxygen and glucose and produces carbon dioxide and water. b. The chemical energy of glucose

Cell Respiration Respiration is the process by which organisms burn food to produce energy. The starting material of cellular respiration is the sugar glucose‚ which has energy stored in its chemical bonds. You can think of glucose as a kind of cellular piece of coal: chock-full of energy‚ but useless when you want to power a stereo. Just as burning coal produces heat and energy in the form of electricity‚ the chemical processes of respiration convert the energy in glucose into usable form. Adenosine
