What is the function of enzymes in a living system?

Enzymes speed up metabolic reactions necessary for life. Without them, certain vital processes would not take place and the body would be unable to function.

Difference enzymes work better under different conditions. Where in a human body might it be beneficial to have enzymes work in very acidic environments?

In areas, like the stomach, that have a pH of two would benefit by having enzymes that function well in acidic environments. An example of such an enzyme is pepsin.

There is a large amount of catalase found in a human liver. Does the liver break down more hydrogen peroxide in the summer or winter? Explain your answer.

More hydrogen peroxide will be broken down in the summer…show more content…

Potassium permanganate - used to titrate and determine the amount of decomposed hydrogen peroxide.  

Sulfuric acid - was used to stop the reaction with catalase and hydrogen peroxide.  It denatured the enzyme (catalase) and halted the reaction so the amount of hydrogen peroxide decomposed could be measured.  

Before performing part D of the experiment, why was it necessary to establish a baseline?

The baseline is a control and shows the amount of decomposed hydrogen peroxide in the initial sample.  

You may have observed the reaction of naturally occurring catalase in tissue from either liver or potato. Design an experiment to determine if the amount of catalase varies from tissue to tissue (e.g. 200 g of the liver compared to 200 g of potato).  

Put the 100 g of potato in 1 petri dish and 100 g of the liver in another petri dish. Then put equal amounts of hydrogen peroxide for an equal period of time in both dishes. Drain the dishes and titrate them with potassium permanganate simultaneously. The numbers can now be compared using the steps in the sample calculation above in the lab report. In order to compare perform a potassium permanganate titration on pure hydrogen peroxide.  

Of the thousands of enzymes known, there is a family of enzymes called proteases that catalyze a reaction of breaking down proteins. What do you think would happen if you added a protease to your sample of catalase before proceeding with your experiment?  

The catalase would be broken

how does earths axis affect our seasons

Answers

When the axis is towards the sun it is summer for that hemisphere and when it pointed away it is winter. The axis tilts affect our seasons due to it either being point towards, away from it or in the middle.
Throughout the year, different parts of earth receive the suns most direct rays. The earths tilting is what gives us 4 seasons by how tilted we are to the sun.

Some species of hares are brown most of the year, but change color to white in the winter. This allows them to
blend in through the seasons.

What factor must Planet X have in order for seasons to occur?


A. The planet must be spherical in shape.

B. The planet must be tilted on its axis.

C. The planet’s orbit must not be too elliptical in shape.

D. The planet must have liquid water on its surface.

Answers

Answer:

The answer is C

Explanation:

The correct option is The planet’s orbit must not be too elliptical in shape.

What is atmosphere?

The gases that make up the planet's atmosphere are mixed together. The Earth's atmosphere contributes to the viability of life.

In addition to giving us air to breathe, it protects us from the majority of the Sun's harmful ultraviolet (UV) radiation, increases the surface temperature of our planet by around 33° C (59° F) due to the greenhouse effect, and mainly eliminates dramatic temperature variations between day and night.

There is an atmosphere on each of the other planets in our solar system, but none of them has the same proportion of gases or layered structure as Earth's atmosphere.

Therefore, The correct option is The planet’s orbit must not be too elliptical in shape.

Water is a polar molecule because

Answers

Answer:

Water is a polar molecule because of its unequal sharing of electrons.

Answer:

The reason why Water is considered a polar molecule is because of Unequal sharing of electrons.

Explanation:

This makes the oxygen end of the molecule slightly negative. Since the electrons are not near the hydrogen end as much, that end is slightly positive. When a covalent bonded molecule has more electrons in one area than another, it is called a polar molecule.

The cell will shrink as the solvent from low concentration solute will move towards the high concentration solute.

What is osmosis ?

Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.

Since the solute concentration in the muscle cell is just 2%, and the muscle cell is dipped in a solution that contains 5% solute, the solvent will flow from the muscle cell into the solution. This will result in the muscle cell becoming smaller until the concentration of solutes on both sides is equivalent.

Answers

Answer:

Decodes the sequence of bases on the mRNA and then creates specifc proteins

Explanation:

Decodes the sequence of bases on the mRNA and then creates specific proteins. Therefore, option (A) is correct.

Ribosomes in eukaryotic cells are responsible for protein synthesis, a crucial process in which they decode the genetic information carried by mRNA molecules. Ribosomes read the mRNA sequence and use it as a template to assemble amino acids in the correct order, forming a polypeptide chain that folds into a functional protein. This process, called translation, occurs in two main subunits of the ribosome, which come together on the mRNA strand.

Ribosomes ensure accurate protein synthesis by matching each mRNA codon with the appropriate amino acid, guided by transfer RNA (tRNA) molecules. Ultimately, ribosomes play a central role in translating genetic information from DNA to create a wide variety of proteins that perform diverse functions within the cell and organism, making them essential components of cellular machinery. Therefore, option (A) is correct.
