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

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;

format of ATP’’ ATP (also known as adenosine tri-phosphate) is produced. Respiration is conducted from the cell membranes inside the mitochondria. Aerobic respiration provides a lot of energy needed per molecule of glucose (the level of ATP produced can be as high as 38 ATP molecules per 1 molecule of glucose. When the body is exercising intensely respiration happens faster and the muscles need more oxygen. Anerobic respiration uses a reaction of glucose and water to make energy it creates by-products

I predict that as I increase the temperature‚ the distance moved by the meniscus will also increase. I believe this will happen as aerobic respiration is taking place. This is respiration involving the consumption of oxygen gas‚ producing carbon dioxide and water‚ as shown below. C6H12O6 + 6O2 --> 6CO2 + 6H2O + 36ATP This process allows energy to be produced in the form of ATP‚ Adenosine Triose Phosphate. This occurs by converting glucose into pyruvate via glycolysis. Pyruvate is then transported

Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

Explain how CO2 enters leaves. What environmental factors control stomatal movement? How are these factors related to physical and chemical properties that control the opening and closing of stomata? CO2 enters leaves through stomata‚ which are small openings in the leaves surrounded by guard cells. These stomata are responsive to light‚ so they open with natural light and close at night. One interesting environmental factor that can control stomatal movement is the overall level of CO2 in the

muscles through red blood cells; this is how muscles get the energy they need‚ to work. (2) Aerobic respiration is the way energy is released from glucose when working muscles contract and relax. Muscles normally work in pairs first one contracts (become shorter and wider) and the other relaxes (becomes longer and thinner) this is how they work when moving bones. (1) Formula for aerobic respiration Glucose + oxygen Carbon Dioxide + water (+ energy) Muscle fatigue and what causes

anaerobic respiration affected by changes in temperature? A: It is affected by temperature change‚ when the temperature rise it increase the rate of the anaerobic respiration‚ up to point. Soon the heat will start putting a lot of stress of the organism and then the rate of the anaerobic respiration will go down‚ more rising in temperature will eventually kill the organism. Q: Based on the conditions of early Earth‚ what conclusion can you draw about the amount of anaerobic respiration that was

aerobic respiration in plants and animals e.g. germinating seeds and mealworms Bio Experiment : Comparing Rate of respiration in mealworms at different temperatures? Mealworms are cold-blooded animals and are unable to maintain a constant core temperature‚ hence respiration would therefore change with temperature. As glucose is oxidised‚ oxygen is used up and carbon dioxide and heat energy is produced. Increment in temperature / production of CO2 or O2 consumption would hence be good indicators
