What is the optimum temperature for pepsin activity in Celsius?
According to Biologists, the optimum temperature for pepsin ranges from 37 degrees Celsius to 42 degrees Celsius which are perfect human body temperatures.
Do microbes require proper temperature for optimum growth?
This depends on the type of microbe because they can grow in a wide variety of temperatures
Why mammalian enzymes have optimum temperatures of approximately 40oC whereas plant enzymes have optimum temperatures of 25oC?
Human body temp is constantly maintained at 37 degrees so our enzymes have evolved to work best at this 'warm' temperature . We like nearly all other mammals are warm blooded. Plants do not have to keep their temperature constant and generally exist in colder conditions and can tolerate far greater deviations in temperature hence their enzymes tend to work best at lower temperatures.
Lipase optimum pH?
A lipase is an enzyme that catalyzes the breakdown of fats. Its optimum pH varies depending on the type of lipase. Pancreatic lipase has an optimum pH of 8.0 while stomach lipase ranges from 4.0 to 5.0.
What is the pH optimum of alpha amylase?
The optimum pH is neutral, 7.
What is the optimum pH for carbohydrate digestion?
carbohydrate digesting enzymes have an optimum pH near neutrality so is for carbohydrate digestion.
How are enzymes influenced by temperature increases or decreases?
For temperatures lower than its optimum, enzymes become inactive. This can be undone by bringing them back to optimum temperature. For temperatures higher than their optimum they are denatured and can no longer function even at optimum temperature.
What effect on bacteria of temperatures below optimum?
Metabolism slows.
What are the three cardinal temperatures?
minimum, optimum and maximum temp
What effect would a higher pH have on the temperatures optimum for invertase?
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
What is a cardinal temperature?
It is the minimum, maximum and optimum temperatures of plant growth and development.
Describe the effect of gradually increasing the temperature on the rate of an enzyme controlledreaction?
Increasing the temperature increases the rate of an enzymeÊcontrol reaction up to a certainÊ optimum level, where further increase causesÊ the rate of reaction to fall sharply. This is because enzymesÊhave optimum temperatures on which they work well, andÊ they are denatured when their optimum temperatures are exceeded.
At optimum light intensity which atmospheric gas most directly influences the rate of photosynthesis?
carbon dioxide
What is the optimum temperature for pepsin activity in Celsius?

Do microbes require proper temperature for optimum growth?
This depends on the type of microbe because they can grow in a wide variety of temperatures
How do plant manufacture their food?
Plants make their own food through photosynthesis. Plants need an optimum temperature (23-25 c), carbon dioxide and optimum light intensity (about 40%) to begin the process of photosynthesis.
What is the difference between thermophilic and thermoduric bacteria?
Thermophilic bacteria have growth temperatures that range from 45C to 85C, with an optimum temperature of about 60C. Thermoduric organisms can survive at extreme temperatures, e.g. pasteurization, but cannot grow.
