The Effect of Solute Concentration on the Rate of Osmosis · Temperature affects osmosis, because the greater the temperature, the greater the energy (which must be heat), the faster the molecules under the influence of the heat will move, and the faster they will diffuse across the membrane. This isn't the only worry, because heat can have a physically detrimental affect on this experiment as well.

Effect of temperature on enzyme activity Effect of temperature on enzyme activity. The temperture of a system is to some extent a measure of the kinetic energy of the molecules in the system. Thus the lower the kinetic energy, the lower the temperature of the system and, likewise, the higher the kinetic energy, the greater the temperature of the system.n order to convert substrate into product, enzymes must collide with and bind to the substrate at the active site. Increasing the temperature of a system will increase the number of collisions of enzyne and substrate per unit time. Thus, within limits, the rate of the reaction will increse.

Why does temperature affect the solubility of a solute in solvent? Best Answer: remember that the higher the temperature the higher the random translational motion of the molecules. Essentially the molecules are zipping around faster, at higher temperatures, therefore creating more area for the solute to dissolve in the solvent. This is the way you can create a supersaturated liquid.

How does osmolarity affect bacterial growth? Most bacteria do not need to regulate their internal osmolarity with precision because their cell walls can sustain a considerable osmotic pressure. The availability of water is the critical factor that affects the growth of cells. The availability of water is measured by the water activity, #A_w#. For pure water, #A_w# is 1.00. As the osmolarity increases, the #A_w# decreases. Some typical #A_w# values are. blood, 0.99.

The Effects of Temperature on Muscular Contraction Temperature. Temperature can greatly affect the ability of your muscle to contract. It is more difficult for muscle to contract in cold temperatures than in warmer conditions. Temperature affects the ease with which oxygen is released from hemoglobin.At cold temperatures, oxygen is more tightly bound to the hemoglobin and does not release as easily.This slower rate of release leads to a lower amount of oxygen available to your muscles, making contraction more difficult.emperature affects the ease with which oxygen is released from hemoglobin.

Does Temperature Affect Dissolving? Increased molecular motion causes more solvent molecules to contact solute molecules and pull on them with more force, usually resulting in more dissolving. Since different substances are made from different atoms, ions, or molecules, increased temperature will affect their dissolving to different extents.

Water Temperature Water temperature can affect conductivity in two ways. As conductivity is measured by the electrical potential of ions in solution, it is affected by the concentration, charge and mobility of those ions 11. Water temperature affects viscosity, which in turn affects ionic activity and conductivity.

How does temperature affect the rate of photosynthesis?   Yes it does,   The rate of photosynthesis in relation to temperature forms a bell curve.   At low temperatures the enzymes responsible for photosynthesis have very … little energy so the rate of photosynthesis is very slow. if it is cold enough for water to freeze it can be very harmful to a plant.

How does temperature of water affect the dissolving rate of sodium chloride (salt)? ? Report Abuse. Temp does affect dissolving rate. at higher temps, the water molecules move around faster so when something is put in, like salt, it will disolve or spread around faster than lower temps. At lower temps the molecules slow down, so salt or other materials do not disolve or disperse as quickly.he higher the temperature the more solute (salt) you can dissolve in your solvent (water.) In some cases if you raise the temperature it can become saturated and when it cools it becomes super-saturated.

Factors Affecting Solubility As the temperature of a solution is increased, the average kinetic energy of the molecules that make up the solution also increases. This increase in kinetic energy allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions. The average kinetic energy of the solute molecules also increases with temperature, and it destabilizes the solid state. The increased vibration (kinetic energy) of the solute molecules causes them to be less able to hold together, and thus they dissolve more readily.

Diffusion and osmosis The pressure inside the cell increases. The inelastic cell walls can withstand the pressure and the cell wall becomes very turgid(rigid). When all of the cells are fully turgid, the plant is frim and upright. But if the water is in short supply, cells will start to lose water by osmosis. They lose turgor pressure and become flaccid(not rigid) and the plant begins to wilt.

The Importance of Homeostasis The shape of the active site is affected by pH. This is why enzymes will only work at a specific pH, as well as a specific temperature. Change the pH and the enzyme stops working. Increasing the temperature to 60°C will cause a permanent change to the shape of the active site.he important part of an enzyme is called the active site. This is where specific molecules bind to the enzyme and the reaction occurs. Anything that changes the shape of the active site stops the enzyme from working.

Enzyme activity----affected by temperature, pH and substrate concentration? If you change pH or temperature, the enzyme loses its conformation (shape) and so becomes non-functional. Effect of substrate concentration: initially, the more substrate you add will cause enzyme activity to increase, upto a certain point (activity doesn't increase infinitely).

How does temperature affect photosynthesis? As the temperature increases, the enzymes get more energy so the rate of photosynthesis increases. If it gets too hot the enzymes begin to lose their shape (denature). This means they are unable to function properly and the rate of photosynthesis decreases again.

How does temperature and salinity affect water density ? Since this one has more marbles for each box part (4) than the first one (3), we can say that the second one is DENSER. Salinity adds to mass (no. of marbles) but not to the volume (size of box). Thus, the more salinity, the denser. Temperature may also affect water density. When the temperature is high, molecules in water disperse and move around more rapidy than they usually do in order to spread the heat energy.
