Explain how a lower temperature leads to slower nerve impulse conduction. Explain how the body metabolises the products of digestion How are transgenes put into an organism? How do enzymes work? How does fermentation work? Explain how the hormone ADH helps to carry out osmoregulation in the hum...
What can affect the function of enzymes? Why do enzymes change with ambient temperature? (a) What can affect the function of enzymes? (b) Why do enzymes change with ambient temperature? How does an enzyme work to increase the rate of a reaction?
Some animals might react to temperature. Some animals could also be responding to internal cues, such as the number of fat reserves stored in their bodies. In the absence of all external stimuli, many animals still know when to migrate and when to head home due to their internal circadian ...
The muscle tissue begins to lose its stiffness after about 36 hours, and within about 72 hours of dying, the body's rigor mortis will subside. As the cells die, bacteria within the body begin breaking them down. Enzymes in the pancreas cause the organ to digest itself. The body soon ...
Translation: The mRNA is carried back out of the nucleus by the cell's enzymes. The virus then uses the cell's natural protein-making mechanisms to make long chains of viral proteins and enzymes. Assembly: RNA and viral enzymes gather at the edge of the cell. An enzyme called protease cu...
is between 35 and 40 degrees Celsius. Increasing temperature within this window increases the rate of reaction, because it excites molecules and increases the rate at which enzymes/reactants collide and react to make product. However, increasing temperature too much may denature the enzyme and prev...
In general, breathalyzers can detect alcohol in a person's system 15 minutes after consumption and about 12 to 18 hours later. How do breathalyzers detect alcohol? Since alcohol is a volatile substance (it evaporates at room temperature) its fumes start mixing with your breath. The more ...
Temperature Acclimation: Adjusting to a new environmental temperature over a period of time. Physiological acclimation to a new temperature has several aspects: 1) Cells may increase the production of certain enzymes. 2) They may produce the same enzyme but at a different temperature optima. 3) ...
Alpha-amylaseandbeta-amylase, theprimary starch-converting enzymes, exhibit optimal performance within a specific pH range, generally agreed to be between 5.2 and 5.6. Beta-amylase, which favors a slightly lower pH around 5.2, tends to produce a more fermentable wort, leading to a drier beer. ...
(a) What can affect the function of enzymes? (b) Why do enzymes change with ambient temperature? Why are enzymes important to humans? a. because they are proteins b. because they can evade the laws of thermodynamics c. because they allow reactions to occu...
