Ben was training for a cross-country bicycle race. During his practice run, Ben's tire went flat and he fell off of his bike, cutting both knees. He was worried that he would not be able to compete in the race being held in two weeks, but his father told him not to worry: His knees would be healed by then. What process is responsible for new tissue growth and the healing of Ben's knees?a. mitosis
b. meiosis
c. duplication
d. transcription

Answers

The answer is (a.) Mitosis

Ben's cut on his knees will be healed because of mitosis. Mitosis is responsible for the new tissue growth for the healing of Ben's cut. Mitosis is referred as the fundamental process if life. In Mitosis, a single cell will grow and reproduce to two identical cells. 

A) mitosis is the answer

Which explanation best explains the role of enzymes as catalysts in living systems?Select one of the options below as your answer:



A.
Enzymes accelerate chemical reactions without getting used up in the process.




B.
Enzymes accelerate chemical reactions by getting used up in the process.




C.
Enzymes decelerate chemical reactions by getting used up in the process.

Answers

I think the correct answer from the choices listed above is option A. The role of enzymes as catalysts in living systems is that they  accelerate chemical reactions without getting used up in the process. Enzymes hasten chemical reactions by providing alternative path for the reaction.
A. is the correct answer

Which provides long-term energy storage?a. Glycogen
b. Glucagon
c. Glucose
d. Cellulose

Answers

Glycogen provides long-term energy storage.

Glycogen is an example of a carbohydrate which is a polysaccharide that acts as a long-term energy storage compound in animals.

Further Explanation

  • Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
  • Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.  

Energy source in animals

  • Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
  • These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
  • When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
  • Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.

Energy source in plants

  • In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.  

Why other Choices are incorrect:

Glucagon  

  • Glucagon is the hormone that increases the blood glucose level to avoid it from dropping below optimum level.
  • The hormone acts on the liver to stimulate the breakdown of glycogen to glucose, a process called glycogenolysis, and the glucose is released to the blood stream.

Glucose

  • Glucose is a simple carbohydrate classified as monosaccharides. It acts as the short term source of energy in both plants and animals.
  • It is readily broken down during the process of cellular respiration to yield energy in the form of ATP, which is then used to drive cellular processes.

Cellulose

  • Cellulose is an example of a complex carbohydrates known as polysaccharides.
  • It is found in plants cells lining the cell wall of all plant cells which is one of the key distinguishing feature between plant cells and animal cells.

Topic: Cellular respiration

Glycogen serves as a long-term energy storage molecule in animals, including humans. Therefore option A is correct.

It is a complex carbohydrate made up of glucose units linked together in a branched structure. When dietary glucose levels are high, excess glucose is converted into glycogen and stored primarily in the liver and muscles.

This stored glycogen can be broken down into glucose when energy is needed during periods of fasting, exercise, or other metabolic demands.

Glucose, on the other hand, is a simple sugar that serves as an immediate energy source, while glucagon is a hormone involved in regulating blood glucose levels. Cellulose, a structural polysaccharide, is not used for energy storage in animals.
