How does surface area affect enzyme activity?
Discussion: The rate of enzyme activity increased along with the surface area of substrate. As particle size decreased, the surface area increased. The larger the number of particle collisions per second, the faster the rate of enzyme activity (Clark, 2002).
How does surface area affect catalase?
A larger surface area means that there will be more catalase molecules coming in contact with the reacting substrate, hydrogen peroxide.
Does size of enzyme affect enzyme activity?
Changing the pH will affect the charges on the amino acid molecules. Amino acids that attracted each other may no longer be. Again, the shape of the enzyme, along with its active site, will change. Extremes of pH also denature enzymes….The effect of pH.
| Enzyme | Optimum pH |
|---|---|
| Pancreatic protease (trypsin) | 7.5–8.0 |
Does surface area affect pH?
The surface area measurements at lower pH are lower than those measured at higher pH due to the replacement of Na(+) ions from interlayers at lower pH which may be followed by the reduction of repulsive forces.
What are two important influences on enzyme activity?
Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
What are the environmental factors that can influence enzyme activity?
Enzyme activity is influenced by several environmental factors such as temperature, salt, pH and substrate concentration. Low or high values of these factors will cause alteration in a structure that will further disrupt the functioning. Therefore, the correct answer is (e) temperature, pH, and salt.
What is the effect of surface area on enzyme activity?
This is because the more surface area is the more chance there is that the moleculeswill collide with each other. Whereas if there is less surface area there is less to collide with. If there was less surface area then there would be a less likely chance that the enzymes would meet their substrates so they could react.
What are the factors that affect the activity of an enzyme?
There are five factors that effect enzyme activity. They are: The factor I am changing is surface area of potato containing Catalase. By increasing the surface area of the potato, you make more Catalase molecules be exposed to hydrogen peroxide.
What is the active site of an enzyme?
All enzymes have an active site. This is where another molecule (s) can bind with the enzyme. This molecule is known as the substrate. When the substrate binds with the enzyme, a product is produced. Enzymes are specific to their substrate, because the shape of their active site will only fit the shape of their substrate.
Does surface area affect the reaction rate of the enzyme catalase?
This experiment tested the effect of different surface areas, temperatures, and pHs on the reaction rate of the enzyme Catalase, as well as the reusability of the enzyme. Following are the hypothesis: As the surface area gets larger, the reaction rate will increase.
