Rate as a term has to do with the time of something therefore how fast the photosynthesis takes place. The amount of glucose produced by the plant is how we measure the rate of photosynthesis. There are three factors that affect Photosynthesis, which are temperature, light intensity and concentration of carbon dioxide. In any situation any three of these factors can be limiting or directly affect the rate of photosynthesis. This is very important for farmers as they use the three limiting factors to increase the rate of photosynthesis to increase the produce of the crop. The factor that is the closest to the minimum value is the limiting factor in the process of photosynthesis. The factor that becomes the limiting factor is the one that is …show more content…
Temperature affects enzymes in a big way. If the temperature is too cold for enzymes they move around much slower to meet the substrate, which makes the reaction much slower. The rate of reaction increases though if the temperature increases. This happens because when the temperature is higher than the enzymes move around much faster and they have a higher chance to collide with the substrate. Enzymes however are proteins and at high temperatures the proteins will break down until they become denatured. The substrate will not be able to fit in the enzymes active site as it becomes distorted and therefore no reaction will occur.
Carbon Dioxide Concentration: The rate of photosynthesis increases as the carbon dioxide increases with it. The rate gradually slows down and at a certain carbon dioxide concentration the rate of photosynthesis remains constant. This is because the rise of carbon dioxide has no effect as light intensity and temperature becomes limiting
As the substrate in increased the initial reaction rate will increase until it is fully submerged and then will not increase any more. The relationship is linear. As the substrate concentration increases, the initial reaction rate increases.
The rate of photosynthesis is affected by environmental factors like light intensity, light wavelength, and temperature. This experiment will test the
Enzyme saturation occurs because there is a limit on how fast a reaction can proceed and at some substrate concentrations all active sites on the enzyme are engaged.
Temperature: Temperature is an extremely important variable to consider, as it can affect the rate of reaction in a number of ways. If the temperature of a system is increased, more molecules will reach the activation energy and the rate of reaction will increase. The number of collisions will also increase. As enzymes must collide with substrates, an increase in temperature and thus kinetic energy will result in more collisions occurring in a given time. Increasing the temperature will also increase the heat of the molecules.
Based on your data, draw a conclusion regarding how light intensity affects the rate of photosynthesis.
reaction rate increases. If the temperature of an enzyme gets to high the reaction rate will slow
As the temperature increases, so will the rate of enzyme reaction. However, as the temperature exceeds the optimum the rate of reaction will decrease.
Temperature affects the rate of which the enzyme reacts, enzymes react typically faster in hotter temperatures than colder. Ph levels that are extremely low or high can stop enzyme activity completely or slow them down.If there is more enzyme concentration the reaction is quicker because enzymes become constant. Also if substrate activity increases, so the reaction time speeds up until maximum is reached.
Introduction We hypothesize that different variations of heat will affect the rate of photosynthesis, specifically the more heat, the more photosynthesis, but only to a certain temperature. We believe this because within chloroplast
Photosynthesis occurs in the palisade mesophyll of plant leaves. During photosynthesis, carbon dioxide is broken up into 6 carbon for the sugar molecule and 12 oxygen. In this lab, I determined the rate of photosynthesis in spinach
The enzyme does this by lowering the activation energy required for the chemical reaction. This allows the cell to increase the rate of chemical reactions while reducing the energy required for this to take place. The environment an enzyme is in will determine the rate of the reaction. Different temperatures
Enzyme catalysis is dependant upon factors such as concentration of enzyme and substrate, temperature and pH. These factors determine the rate of reaction, and an increase in temperature or pH above the optimum will
At low temperatures (5oC-15oC) the rate of photosynthesis will be slow, as the enzymes of the plant do not have enough energy to meet substrate molecules. However, as the temperature increases, there will be a greater rate of photosynthesis, especially as the enzymes approach the optimal temperature. Although once the increase in temperature has gone past the optimal temperature, enzymes will begin to denature and the rate will decrease until there is little or no oxygen being produced by
The concentration of enzymes and substrates affects the rate of reaction, as the concentration of the enzyme and substrate is increased, the velocity of the reaction proportionately increases. By increasing the concentration of substrate it will gradually increase the velocity of enzyme reaction within the restricted range of substrate levels.
Concentrations: The amount of concentration is another example which could speed up the rate of reaction. When you put more of a substance you will have more collisions taking place and as you have more collisions taking place the rate of reaction will speed up. WHen you want a rate of reaction to be slower you would only add a few drops to another solution but if you want it to happen quicker you put a bigger amount/a
