What affect does temperature have on cellular enzyme activity?
Changes in temperature can alter the rate of enzyme activity. Generally, enzymes function optimally at a specific temperature range, beyond which they can become denatured, leading to a loss of function. Lower temperatures typically slow down enzyme activity, while higher temperatures can increase the rate until a threshold is reached and enzyme activity declines.
What happens at the optimum temperature at enzyme?
It means the highest (and best) temperature an enzyme can work until it gets denatured (active site is re-shaped therefore substrate is unable to fit into it anymore). Hope it helped :)
Define total enzyme concentration?
The optimum pH and optimum temperatures of an enzyme are simply levels that the enzyme work most effectively at. These levels contribute to factors such as the enzyme's protein structure. Different levels of pH and temperature can alter the integrity of the protein, this process is called denaturation. When an enzyme undergoes denaturation, its level of activity is inhibited by failure of the substrate to effectively attach itself to the active site.
What name is given to the molecules made in an enzyme controlled reaction?
The molecules made in an enzyme-controlled reaction are usually referred to as products. These products are the result of the substrate molecules being transformed by the enzyme during the reaction.
A given enzyme works on?
specific substrates to catalyze a biochemical reaction. Each enzyme has a specific substrate or group of substrates that it acts on, and the enzyme's active site is designed to bind to these substrates. This specificity ensures that the enzyme functions effectively in the body.

What is the optimal pH for maintaining a stable enzyme activity at a given substrate concentration of 10 mM?
The optimal pH for maintaining stable enzyme activity at a substrate concentration of 10 mM is typically around pH 7. Enzymes function best within a specific pH range, and deviations from this range can affect their activity. Maintaining the pH at around 7 helps to ensure that the enzyme is working efficiently at the given substrate concentration.
What is the optimum temperature of an enzyme?
Enzymes are sensitive to temperature enzyme has its optimum temperature for its maximum activity,above and below this temperature its rate of reaction decreases.Most of enzymes are highly active at about 37C and are completely destroyed at 100C,whereas at minimum i.e.0C, activity is reduced to minimum but enzymes are not destroyed.

What is the optimum salt concentration for catecholase?
The optimum salt concentration for catecholase is 2%. Absorbance rates in a reaction in which involves the catecholase enzyme peak when the salt concentration is at 2% given other factors remain constant.

What factors affect the rate at which an enzyme works?
Very basically: * specificity - the better 'fit' the substrate, the higher the rate of catalysis. * temperature - higher temp = more kinetic energy = faster eaction. However, too high and the enzyme becomes irreversibly denatured and will not work at all. (denatured = the folding of the peptide chains are disrupted, meaning that the shape changes and the substrates no longer fit). The temperature at which the reaction occurs at the fastest rate is called the optimum temperature. * pH - enzymes have specific pH that they work best at (the optimum/optimal pH), as pH can also affect the bonds holding the tertiary structure together (especially ionic bonds), denaturing the enzyme. * concentration of enzyme and substrate - rate of reaction is proportional to the enzyme/substrate concentration. However, at a given enzyme concentration, substrate conc is proprtional to rate up to a point when the enzyme becomes saturated and the rate remains constant. * cofactors/coenzymes - some enzymes require interaction with other molecules to show full catalytic activity. * inhibitors - the presence of an inhibitor lowers the rate of catalysis. There are competitive, uncompetitive, non-competitive and mixed inhibitors, they can bind reversibly or irreversibly, at the active site or an allosteric site... That's a very simple, school textbook answer (and I may have forgotten a factor?). For more detail, any biochemistry textbook should be able to help.
What is the name given to the part of an enzyme where the substrate comes into contact it?
The active site is the specific part of an enzyme where the substrate binds and interacts with the enzyme. This is where the chemical reaction facilitated by the enzyme takes place.
Is the optimum growth temp the ideal temp for all cell activities. based on observation of S.marcescens and S.cerevisiae cultures Explain?
The optimum growth temperature is the temperature at which a microorganism grows best, which may not necessarily be the ideal temperature for all cellular activities. In the case of S. marcescens and S. cerevisiae cultures, the optimum growth temperature may differ from the optimal temperature for other metabolic processes such as enzyme activity or protein synthesis. Different cellular activities may have their own optimal temperature requirements beyond just growth.
Some surgical procedures involve lowering a patients body temperature durng periods when blood flow must be restricted. what effect might this have on enzyme-controlled cellular metabolism?
Lowering the body temperature would lower the temperature in the cells, this causes the substrates to slow down, in a sense be less hyperactive, thus lowering the chance that the substrate will come in contact with its given enzyme. This will lower the overall Cellular Metabolism
