What can affect the speed of the enzyme action?
Factors that can affect the speed of enzyme action include temperature, pH, substrate concentration, and presence of inhibitors or activators. Enzymes work optimally within a specific temperature and pH range, and their reaction rate can increase with increasing substrate concentration. Inhibitors can slow down enzyme activity, while activators can enhance it.
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.
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 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.
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
Does enzymatic action in a chemical reaction result in an increase in temperature?
Yes it can, but more commonly an increase in temperature increases enzymatic action.
Do Temperature of the cytoplasm influence the action of enzymes?
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
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?
Based on the graph, it can be concluded that one enzyme is more temperature-sensitive than the other. This is evident by the steeper slope of one enzyme's curve, indicating a faster increase in activity with temperature. Additionally, both enzymes exhibit an optimum temperature where their activity is highest before declining due to denaturation.
What does the body do automatically to increase the body temperature?
Shiver. The muscle action will raise the temperature.

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.

What are characteristics of enzymes?
Enzymes are proteins that act as biological catalysts, speeding up chemical reactions. They are highly specific, meaning they only catalyze one type of reaction. Enzymes can be affected by factors such as temperature and pH, which can impact their function.
