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

What is the full form of DNA ?

DNA stands for deoxyribonucleic acid.

DNA contains the orders that are needed for any organism in order  to develop, survive as well as reproduce. To carry out these duties, DNA sequences are needed to be converted into messages which can be used to produce proteins in  which are the complex molecules that are  doing  most of work in our body.

Since we have two pairs of chromosomes and we also have two pairs of genes in which  one  is from our father and one is  from mother. These pairs of genes then determine certain physical features or traits.

Which process of genetic recombination involves genes from both parents?
crossing over
independent assortment
fertilization
tetrad formation

Answers

Answer:fertilization

Explanation:

The process of genetic recombination which involves genes from both parents is crossing over. This process occurs during prophase I of meiosis, when homologous chromosomes pair up and exchange genetic material.

Explain the process?

A portion of each parent's chromosome is swapped during this process, resulting in two new chromosomal combinations that are distinct from those of either parent. Genetic variety among the progeny is produced as a result of this process, which is advantageous for evolution.

The process of crossing over is random, therefore it is unpredictable which chromosomal segments will be exchanged. This is crucial for fostering genetic diversity because it allows for a wider variety of genetic combinations to be produced when genetic material is exchanged.

As portions of each chromosome will be exchanged during crossing over, this procedure also aids in ensuring that the offspring obtain a combination of genetic material from both parents.

Plants need three things for photosynthesis to occur: water, carbon dioxide and sunlight. How do those things enter a plant? Water, along with important minerals, enters a plant from the soil where the plant's roots act like straws "drinking" it up. Carbon dioxide enters a plant from the atmosphere, and it comes in through the leaves. More specifically, carbon dioxide enters a plant through tiny pores or openings on leaves called stomata. Sunlight, obviously, comes from the sun. But how does it enter the plant to be converted into chemical energy that the plant can use? Well, green plants are green because of a pigment called chlorophyll. That pigment inside of plant cells absorbs the sun's energy, making it possible for photosynthesis to occur.

Based on the passage, if human cells had a lot of chlorophyll, they would most likely

A

Some suggestions for measures that the United States can implement to avoid contributing to greenhouse gases!

Answers

Answer:

1. Increase the use of green renewable energies  

2. Promote recycling  

3. Controlling industrial greenhouse CO2 emissions from the transportation sector  

4. encourage the use of non-polluting means of transport (e.g., walking over road transport)

Explanation:

First, renewable energies are energy sources generated naturally without the use of fossil fuels (e.g., solar energy, wind energy, geothermal energy, etc). Thus, these green energies can replace the use of fossil fuels in a sustainable manner, and therefore reduce the emission of greenhouse gases such as carbon dioxide (CO2). Second, recycling can drastically reduce the amount of energy required to synthesize new products and reduces the need for new materials, being thus also useful to reduce CO2 emissions that result from extracting virgin materials. Third, the industries from the transportation sector produce the largest part of greenhouse gas emissions, thereby encourage the use of green energies in this area may represent a good alternative to reduce CO2 emissions. Finally, it is well known that urban transport generates about 40% of all CO2 generated by road transport, and thereby invest in green transport systems such as bicycling and walking may also represent a useful strategy to reduce CO2 emissions.

WILLL GIVE BRAINLIST!!! Suppose mechanical weathering breaks a rock into pieces. How would this affect the rate at which the rock weathers chemically? How do chemical and physical weathering differ? Explain your answer in at least 3 sentences.

Answers

Answer:

Explanation:

Mechanical weathering increases the rate of chemical weathering.

As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more surfaces on which chemical weathering can occur.

Chemical weathering is different from mechanical weathering(physical weathering )  because the rock changes, not just in size of pieces, but in composition.

That is, one type of mineral changes into a different mineral.

Chemical weathering works through chemical reactions that cause changes in the minerals.

How do shale oil and tar sands compare to conventional
(regular) oil deposits?

Answers

Answer:

Oil shale is a form of sedimentary rock that contains kerogen, which is released as a petroleum-like liquid when the rock is heated. Tar sands are a combination of clay, sand, water and bitumen, which is a heavy hydrocarbon.

Additional info:

The term oil sands refers to a particular type of nonconventional oil deposit that is found throughout the world. Oil sands, sometimes referred to as tar sands, is a mixture of sand, clay, other minerals, water, and bitumen. The bitumen is a form of crude oil that can be separated out from the mixture.

The primary distinction between crude or conventional oil and shale oil is the way it collects. The oil in shale is typically found in smaller batches. As a result, shale oil often needs to be fractured so that the oil trapped within the shale can be recovered.

Answer:

Explanation:

Oil shale is a form of sedimentary rock that contains kerogen, which is released as a petroleum-like liquid when the rock is heated. Tar sands are a combination of clay, sand, water and bitumen, which is a heavy hydrocarbon. Like the kerogen in oil shale, tar sands' bitumen can be upgraded to synthetic crude oil.
