A change in the rate of enzyme action in aquatic invertebrates would most directly result from a change in what?
A change in the rate of enzyme action in aquatic invertebrates would most directly result from a change in temperature, pH, or substrate availability in their environment. These factors can influence the activity and efficiency of enzymes in these organisms.
What are 3 characteristics of enzymes?
Enzymes are biological catalysts that speed up chemical reactions in living organisms. Enzymes are specific in their action, meaning they catalyze specific reactions and substrates. Enzymes can be regulated by factors such as temperature, pH, and inhibitors.
How does temperature change the affect of peroxidase enzymes?
Temperature can affect peroxidase enzymes by influencing their activity level. Generally, increasing temperature can initially enhance enzyme activity up to a point, called the optimal temperature. Beyond the optimal temperature, the enzyme may denature and lose its functionality.
What statement is true of enzymes?
Enzymes are biological catalysts that speed up chemical reactions in living organisms by lowering the activation energy. They are specific in their action, meaning they catalyze specific chemical reactions. Enzymes can be denatured by extreme pH or temperature changes, affecting their function.
What happens to enzymes at -0 degrees?
At 0°C enzyme action is low because the movement of molecules is low. This causes the collision frequency between enzyme and substrate to be low. Increasing the temperature speed up the movement of molecules and thus the collision frequency increases therefore enzyme action increases. Human bio enzymes work best at 37 degrees Celsius. As the temperature raises the shape of the enzyme changes and the enzyme becomes denatured. Temperature above 50 degrees Celsius will denature most human enzymes.

A change in the rate of enzyme action in aquatic invertebrates would most directly result from a change in temperature, pH, or substrate availability in their environment. These factors can influence the activity and efficiency of enzymes in these organisms.
Do Temperature of the cytoplasm influence the action of enzymes?
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
Which enviromental factor can change the activity of enzymes?
Temperature
The graph below shows how two different enzymes react with a substrate as the temperature increases. Based on the results what conclusion can be drawn about the action of the enzymes as the temperatur?
enzyme B stays effective at higher temperatures than enzymes A
What is the quickest most effective way to inactivate Proteinase K?
As with most protein enzymes change the temperature or change the pH significantly.
What are two environmental conditions that can cause enzymes to change there shape?
Extreme temperatures and pH levels can cause enzymes to change their shape, leading to denaturation and loss of function. Additionally, high salinity levels can also disrupt the structure of enzymes, affecting their activity.

What is the temperature that promotes enzymatic action?
Different enzymes are most efficient at different temperatures, these are called 'the optimum temperature'. A temperature far lower than this will cause the rate of reaction to slow until barely noticable. A temperatuere far higher than this will cause the shape of the enzyme to change and the enzyme will become denatured.
How can enzymes be inactived?
All enzymes work best at a certain temperature and pH. They also need a substrate to work on. A change in pH or temperature will inactive it by denaturing it. If the substrate is very low in quantity or is absent, the enzyme will be inactive.
Are enzymes permanently inactivated by high temperature extremes or are changes in the enzymes reversible?
Enzymes are permanently inactivated by high temperature extremes. They are denatured.
Why is temperature a factor of cellular respiration?
Temperature can effect enzymatic action of all cellular activities to a great degree. Typically increasing the temperature will stimulate enzymes while decreasing it will hinder their activity. If the temperature is too high the protein enzymes will denture and become useless. If the temperature is too low the activation energy required to initiate enzyme action will not be able to be overcome and the enzymes will be rendered inoperable.
What causes tomatoes to ripen much more slowly in a refrigerator than they do if left on a table at a room temperature?
Low temperatures reduce the action of ripening enzymes. When tomatoes are stored in a refrigerator the colder temperature causes ripening enzymes to slow down, which slows the ripening process.
