No, pepsin is not the substrate in the experiment with BAPNA. BAPNA is the synthetic substrate used in this experiment to test the activity of the enzyme pepsin by measuring the rate of substrate cleavage. Pepsin acts on BAPNA as the enzyme, not the substrate.
Enzyme concentration has no effect on the rate of an enzyme-catalyzed reaction after reaching a saturation point where all enzyme active sites are occupied. At this point, adding more enzyme will not increase the reaction rate further.
The rate of an enzyme-catalyzed reaction is often referred to as the enzyme's catalytic activity or turnover rate. It is a measure of how quickly the enzyme can convert substrate molecules into products.
Sand is used in an enzyme rate of reaction lab to provide a stable surface for the enzyme reaction to occur. It helps to maintain a consistent and controlled environment for the reaction by providing a solid base and preventing any unwanted movement or fluctuations. This ultimately allows for more accurate measurements and observations of the enzyme reaction rate.
An enzyme
Well using less pepsin means you have less of the enzyme. Now if you keep the substrate / enzyme ratio constant there won't be anything changing. If you however decrease the pepsin amount, there will be less active sites for the same amount of substrate to bind. ---> slower reaction

The enzyme pepsin shows the greatest change in its rate of action with the least change in pH. Pepsin works optimally at a highly acidic pH of around 2, and even small changes in pH can significantly impact its activity.

Noncompetitive inhibitors decrease the rate of an enzyme reaction by bonding to an enzyme somewhere other than the active site, deforming it and permanently disabling the enzyme, so that enzyme can never function again, so the rate of reaction decreases.
Increasing enzyme concentration typically leads to more enzyme-substrate complexes, thereby increasing the rate of the reaction. In the presence of excess substrate, the reaction rate is limited by the enzyme concentration, resulting in a proportional increase in the rate of the reaction with increasing enzyme concentration. This relationship holds until all substrate molecules are bound to enzyme molecules, reaching saturation.
Tobin can conclude that the reaction rate is directly proportional to the enzyme concentration when excess substrate is present. This is because at higher enzyme concentrations, all substrate molecules are already bound to enzyme active sites, leading to a maximal reaction rate even with excess substrate.

The rate of enzyme reaction is increased when the substrate concentration is also increased. However, when it reaches the maximum velocity of reaction, the reaction rate remains constant.
As the substrate concentration increases so does the reaction rate because there is more substrate for the enzyme react with.
There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.
The initial rate of an enzyme-catalyzed reaction depends on the enzyme concentration, substrate concentration, temperature, and pH of the reaction environment. These factors can influence the rate at which the enzyme binds to the substrate and catalyzes the reaction.
