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;

ABSTRACT The glycolysis pathway is nearly universal in biological systems. Glycolysis is the sequence of reactions that converts glucose to pyruvate with the concomitant formation of ATP. Three fates of this pyruvate produced exist. In this practical the production of pyruvate and acetaldehyde by fermentation of glucose is established. A series of test tubes was set up each containing glucose and yeast suspension in buffers at different pH values. These test tubes were incubated for an hour at 37℃

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

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.

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

how starch and cellulose are treated to allow them to be used by the yeast? One potential ethanol feedstock is starch. Starch molecules are made up of long chains of glucose molecules. Thus‚ starchy materials can also be fermented after breaking starch molecules into simple glucose molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch
