It depends on the nature of the catalyst. For instance, most organic catalysts, known as enzymes, are proteins folded into a very specific shape. Higher temperatures can cause some of these enzymes to lose their shape, thus becoming ineffective.
On a different note, higher temperatures increase the rate of most reactions by providing more energy to the molecules so they may reach activation energy. However, this phenomenon is independent of catalytic action.
What else can I help you with?
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
Why is the required water temperature higher when sanitizing dishes in a high-temperature dishwashing machine than when sanitizing dishes manually?
The required water temperature is higher in high-temperature dishwashing machines because they rely on heat to kill bacteria and sanitize dishes effectively. These machines typically achieve temperatures of 180°F (82°C) or higher, allowing for rapid heat transfer and thorough sanitization in a shorter time. In contrast, manual sanitization often uses lower temperatures, around 171°F (77°C), combined with prolonged exposure to ensure effective disinfection. Additionally, the mechanical action of the machine helps remove debris more effectively, justifying the higher temperature requirement.
Which type of climate has the greatest amount of rockweathering caused by frost action?
The type of climate that experiences the greatest amount of rock weathering due to frost action is the subarctic and temperate climates, particularly those with frequent freeze-thaw cycles. In these regions, temperatures fluctuate around the freezing point, allowing water to infiltrate rock cracks, freeze, expand, and eventually cause fragmentation. This process is most effective in areas with sufficient moisture and seasonal temperature variations.
Can cold temperature denature a protein?
Cold temperature can slow down the movement of molecules in a protein, reducing its activity but typically doesn't denature the protein unless it is subjected to extremely low temperatures for an extended period of time. However, freezing temperatures can disrupt the structure of cells and tissues by forming ice crystals, which can ultimately lead to denaturation of proteins.
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.
Based on the results of what conclusions can be drawn about the action of the enzyme as the temperature increase?
enzyme A becomes less effective earlier than enzyme B enzyme b stays effective at higher temperatures than enzyme a
How will you be able to tell which ion is responsible for any catalytic action?
Mn2+ ion is responsible for the catalytic action
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
Do Temperature of the cytoplasm influence the action of enzymes?
Yes, enzymes have optimal working temperatures that differ from enzyme to enzyme
What is a substance that slow or stop enzymes catalytic action?
inhibitors
What conclusion can be drawn about the action of the enzymes as the temperature increase?
enzyme A becomes less effective earlier than enzyme B enzyme b stays effective at higher temperatures than enzyme a
Can temperatures break down rocks?
Yes. Temperature changes, water, wind, pressure changes, plant and animal action, and gravity are all agents of physical weathing.
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.
What prevents or slows a chemical reaction or interferes witha catalyst's action?
an inhibitor or catalytic poison
Why is the required water temperature higher when sanitizing dishes in a high-temperature dishwashing machine than when sanitizing dishes manually?
The required water temperature is higher in high-temperature dishwashing machines because they rely on heat to kill bacteria and sanitize dishes effectively. These machines typically achieve temperatures of 180°F (82°C) or higher, allowing for rapid heat transfer and thorough sanitization in a shorter time.

What is the motto of Results for Development Institute?
Results for Development Institute's motto is 'Innovative Ideas. Catalytic Action.'.
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.
