Conditions that are likely to increase enzyme activity include optimal temperature and pH levels, as well as the presence of cofactors or coenzymes that help the enzyme function more efficiently. Additionally, a higher substrate concentration can also increase enzyme activity up to a certain point, known as the saturation point.
What else can I help you with?
What effect does an increase in pH have on enzyme reaction?
It will very likely change it in some way. It's impossible to be more specific without knowing what enzyme and what pH.From the optimum conditions, an increase in pH will increase the number of OH- ions, and these will affect the charge of areas on the tertiary structure of the protein (remember that enzymes are proteins). This will cause a conformational (shape) change in the protein (enzyme), and therefore denatures it, as the active site is no longer complimentary to the substrate. This will lead to fewer Enzyme-Substrate complexes per second when using a lot of enzymes, and will decrease the rate of the enzyme reaction.
Which curve represents the behavior of an enzyme taken from a bacterium that lives in hot springs at temperatures of 70 or higher?
The enzyme would likely exhibit a high optimal temperature and increased thermal stability. Therefore, its enzyme activity curve would likely show a higher peak and be shifted towards higher temperatures compared to enzymes from organisms living in milder conditions.
If a base is added gradually to a solution with a pH of 6 containing enzyme C and its substrate the rate of action of enzyme C would most likely?
Increase initially due to the pH shift towards the optimum pH range for enzyme C, then decrease as the pH becomes too basic and denatures the enzyme. Enzymes have an optimal pH at which they function most efficiently, and deviations from this pH can impact their activity.
Which graphs likely represents the effect of temperature on photosynthetic reactions?
An exponential graph is likely to represent the effect of temperature on photosynthetic reactions, as the rate of photosynthesis typically increases with temperature up to a certain point before leveling off or decreasing due to enzyme denaturation. The initial increase is due to higher kinetic energy and enzyme activity, while the decrease is a result of enzyme inactivation.
Which hypothesis most likely explains the results at 60C and 70C in relative rate of enzyme action?
The substrate has changed shape because of the high temperature.
What would be the likely outcome if you increased the concentration of substrate for an enzyme in the presence of a noncompetitive inhibitor?
Increasing the concentration of substrate will not overcome the effect of a noncompetitive inhibitor. The inhibitor binds to the enzyme at a site other than the active site, causing a conformational change that reduces the enzyme's activity. Therefore, increasing the concentration of substrate will not result in a significant increase in enzyme activity.

What conditions LEAST likely to denature an enzyme?
low temperatures
Which curve was most likely generated from analysis of an enzyme from a human stomach where conditions are strongly acid?
The curve most likely follows a pH profile where the enzyme shows maximum activity at very low pH values (strongly acidic conditions). This would suggest that the enzyme is optimized to function efficiently in the acidic environment of the human stomach.
What connective tissue cell would most likely increase activity during an infection?
an infection would most likely increase activity in what tissue

Are enzyme inhibitors likely to increase the production of product in a metabolic athway?
No, they decrease it
Which hypothesis most likely explains the result at 60 and 70c?
The hypothesis that enzyme activity is affected by temperature is likely the best explanation for the results at 60 and 70°C. Enzymes have an optimal temperature range for activity, and deviations from this range can decrease enzyme effectiveness. At 60 and 70°C, the enzyme may have been denatured, leading to reduced activity.

Increase initially due to the pH shift towards the optimum pH range for enzyme C, then decrease as the pH becomes too basic and denatures the enzyme. Enzymes have an optimal pH at which they function most efficiently, and deviations from this pH can impact their activity.

What connective tissue cell that would most likely increase its activity during an infection?
Macrophages are connective tissue cells that are part of the immune system and are likely to increase their activity during an infection. They function by engulfing and digesting pathogens to help eliminate the infection.
