Enzyme Activity and pH

Biology
1 answer:
sveticcg [70]3 years ago
3 0

Explanation:

B) After determining the optimum pH, they could vary the temperature of the environment to see if catalase is temperature specific

Enzymes are proteins which catalyze reactions by acting on substrates in order to speed up reactions- like the breakdown of large polysaccharides by amylase. Here, the enzyme catalase facilitates the breakdown of hydrogen peroxide into oxygen and hydrogen. Catalase specificity is affected by pH, temperature and the presence of inhibitors.

In temperatures beyond its optimal range, catalase may undergo changes to its physical structure called denaturation; when denatured, enzymes lose their ability to bind specifically to their substrate -i.e. substrate binding specificity is lost. H2O2 would no longer be able to bind to the active site, and thus would not be broken down.

10 points! When looking out of my back door, I see robins, blue jays, finches, crows, hawks and owls all living in the same area
forsale [732]

The possibility for all of the mentioned birds to live all in a same area is because they are all specialized and occupy a certain niche in the food chain, thus not standing in each others ways when it comes to competition for food.

All of these birds have adapted to be able to survive in their respective environment, developing characteristics that will enable them to be superior in something. Through natural selection, the individuals that were performing better, got the chance to mate, thus the offspring was better adapted and stronger in its niche of the food chain.

The robins and the blue jays are birds that are very opportunistic in their food choice, thus giving them greater flexibility and ability to survive, they mostly feed on worms, insects, fruits, vegetables, so they have a big menu.

The finches are specialized in eating nuts and seeds, thus avoiding the competition with the previous two, thus having that food type for themselves.

The owls and hawks are both birds of pray, but the owls hunt mostly at night, while the eagles during the day. Also, the owls prefer to have rodents as their pray, while the hawks are mostly eating other birds, thus not standing in each other's ways.

20. calculate the molar enthalpy of vaporization of a substance, given that 0.433 mol of the substance absorbs 36.5 kj of energy
Allisa [31]

The molar enthalpy of vaporization of the substance is 84.3 kj/mol.

<h3>What is molar enthalpy of vaporization?</h3><h3 />

Molar enthalpy of vaporization is the energy required to vaporize one mole of a liquid at its boiling point.

0.433 moles of the substance absorbs 36.5 kj of energy when it is vaporized.

1 mole of the substance will absorb 36.5 kJ × 1 /0.433mol = 84.3 kj/mol

Therefore, the molar enthalpy of vaporization of the substance is 84.3 kj/mol.
