Answer:
Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.
For most enzymes to operate in the body, the optimal temperature is 37 degree Celsius or 98 degrees Fahrenheit. Most of the human enzymes have a maximal activity at pH around 7.2, which is the pH of most body fluids. However, there are exceptions such as, pepsin.
which organelles contain enzymes that break down old cell parts?
Explanation:
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts.

A way you could test if bacteria are different is through Gram Staining
Despite all bacteria are prokaryotic organisms, there are thousands of bacteria species and each species has different characteristics.
Moreover, bacteria are classified into two main groups:
Gram-negative bacteriaGram-positive bacteriaThese differ in their structure as gram-positive bacteria have a thick peptidoglycan layer, while gram-negative bacteria have a thin peptidoglycan layer and an external layer.
This key difference is essential when classifying bacteria because there are specific species for each type. Moreover, this can be tested through Gram staining, as this will show gram-positive bacteria as purple and gram-negative ones as pink or red.

Recently, the Supreme Court of the United States reversed a lower court ruling that allowed a company to patent DNA sequences for two cancer genes. The patent prevents other scientists from using these DNA sequences for any reason. The company uses the DNA sequences to market kits used to identify the two types of cancer in humans. The company claims that the gene sequences are its intellectual property. it's owner feels that allowing other people to access the sequences will harm his company financially because the search for the gene sequences was very expensive.but the plaintiff in the case argue that Gene sequences are products of nature that cannot legally be patterned the plaintiff explain to the judge that the kids are very expensive as a result some patients who need these tests cannot afford to have them done.

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

Do micronutrients control bodily functions?
Every single micronutrient is crucial for the health of your body's systems. Getting enough of the various vitamins and minerals is essential for good health and could even aid in the prevention of disease.
This is due to the fact that micronutrients are involved in almost every bodily process.
One of the most important vitamin categories that your body need are micronutrients. They contain minerals and vitamins. The creation of energy, immune system health, blood coagulation, and other processes all depend on vitamins.
In the meanwhile, minerals are crucial for a number of functions, including growth, bone health, fluid balance, and others.

[tex] \huge \mathfrak{{ \pmb{ \underline{ \red{Answer}}}}}[/tex]
The red blood cells and brain are two body tissues that derive most of their energy from glucose.
Glucose is the answer.
The red blood cells and brain are two body tissues that derive most of their energy from carbohydrates. The correct option is C.
What are carbohydrates?Sugar molecules make up carbohydrates, or carbs. Carbohydrates are one of the three primary nutrients included in foods and beverages, along with proteins and fats.
Glucose is created by your body's breakdown of carbs. The primary source of energy for the cells, tissues, and organs in your body is glucose, sometimes known as blood sugar.
Under normal conditions, glucose serves as the brain's main energy source.
Using either glycolysis or oxidative phosphorylation—the latter of which is 15 times more efficient—glucose is used to create energy in the form of adenosine triphosphate (ATP).
In the absence of glucose, the brain has backup energy sources, such as ketones created by fatty acid metabolism, which predominantly takes place in the liver.
These include 3-hydroxybutyrate, acetone, and acetoacetate (3BHM).
Thus, the correct option is C.
