Biology how concentration effects the rate

biology how concentration effects the rate Here is an example of a-level biology coursework on the effect of substrate concentration (hydrogen peroxide) on the rate of activity of the enzyme catalase.

Concentration effects effects of substrate concentration we examined reaction rate at different substrate concentrations our standard tubes contained 1 ml of hydrogen peroxide, and different groups ran reactions with more or less substrate to compare to that because each group tried different volumes of substrate, we. Changing the enzyme and substrate concentrations affect the rate of reaction of an enzyme-catalysed reaction controlling these factors in a cell is one way that an organism regulates its enzyme activity and so its metabolism changing the concentration of a substance only affects the rate of reaction if it is the limiting factor:. One of the most consistent effects of elevated atmospheric co2 on plants is an increase in the rate of photosynthetic carbon fixation by leaves across a range of face experiments, with a variety of plant species, growth of plants at elevated co2 concentrations of 475–600 ppm increases leaf photosynthetic rates by an. Biology growth inhibition of micro freshwater algae exposed to chemical oil dispersants how does the concentration of the oil dispersing agent “corexit 9500” affect the growth rate of scenedesmus obliquus, measured by the number of cells left per cm3 per day ingrid marie garfelt paulsen. Gcse biology what effects the rate of osmosis extracts from this document introduction factors affecting osmosis possible independent variables - these are the factors that could be changed: - surface area: volume of potato - temperature - time: how long the potato piece is left in - concentration of solution - mass of. Factors affecting the rate of photosynthesis 3 carbon dioxide carbon dioxide is used to make sugar in the photosynthesis reaction the concentration of carbon dioxide in the earth's atmosphere varies between 003% and 004% an increase in the concentration of carbon dioxide gives an increase in the rate of.

If there are only five eggs, you have to hunt in the fridge for the eggs once you find them, then you can cook them if the other cooks (other enzymes) find them first, you'll have to wait or hunt for more eggs if substrate concentration is low, enzymes have a lower chance of encountering the substrate, so its activity, or rate of. Temperature, ph and substrate concentration affect the rate of activity of enzymes. A concentration gradient occurs when the concentration of particles is higher in one area than another in passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced. What factor most affects the rate of photosynthesis the main variables which affect photosynthesis are light, water, co2 concentration and temperature on a deeper level, other factors like amount of chlorophyll, availability of nutrients (eg mg is needed for chlorophyll synthesis) will also affect the rate of photosynthesis,.

Explain the effect of enzyme concentration on initial reaction rate (4 marks) as concentration of enzyme increases, so does initial rate of the reaction a point is reached when the curve levels off this is because when there is not very much enzyme and lots of substrate, every active site is full add more enzyme and there. Enzymes and the rate of chemical reactions introduction: enzymes are proteins that speed up the rate of a chemical reaction without being used up enzymes are usually specific to particular substrates the substrates in the reaction bind to active sites on the surface of the enzyme the enzyme-substrate. V the effect of changes in blood urea concentration on the society for experimental biology and medicine (addis, t, and drury d r in blood urea concentration on the rate of urea excretion special conditions which were constant except for variation in the amounts of urea taken subject: dru. Answer: catalase increased the rate of reaction of hydrogen peroxide varying h2o2 experiment: experiment 1: 25 ml h2o2, 15 ml catalase, 325 ml buffer experiment 2: 10 ml h2o2, 15 ml catalase, 25 ml buffer question: how does the concentration of h2o2 affect the reaction in a solution of the enzyme.

Lab: the effect of concentration on the rate of diffusion free biology lab perfect for biology or life science students in grades 8-12 purpose: this experiment will explore the concentration gradient by measuring the rate of diffusion in a number. Doi: 1013140/rg222283092488 vailable from: gabriel latremouille, may 15, 2017 download full-text pdf gabriel latremouille biology sl internal assessment the effect of carbon dioxide concentration on the rate of photosynthesis in cambomba caroliniana plants 1 personal code: fqs223.

In diffusion, atoms tend to spread themselves evenly, as when the smoke moves from the high concentration in the kitchen to a lower concentration all through your home the diffusion rate depends on several factors.

If a selectively permeable membrane separates the two solutions, water moves through it in both directions at the same time however, more water leaves a dilute solution (high water concentration) and passes into a more concentrated solution (low water concentration) than enters it although the water appears to move. Carbon dioxide concentration: the higher the carbon dioxide concentration, the lower the rate of respiration increase in carbon dioxide concentration and absence of oxygen adversely affects the rate of aerobic respiration water: the respiratory rate increases with the increase in water content of the respiring organism. 43 effect of carbon dioxide on the rate of photosynthesis when the concentration of co2 is low the rate of photosynthesis is also low (the plant has to spend time waiting for more co2 to arrive) increasing the concentration of co2 increases the rate of photosynthesis picture experiment place a pond weed elodea.
