A. Review What are the major elements of life?

Biology
1 answer:
tino4ka555 [31]3 years ago
7 0

Answer:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur.

2. Its ability to catenate; its ability to form bonds easily with other elements such as hydrogen, oxygen and nitrogen; its ability to form single, double and triple.

3. Carbohydrates, Proteins, Lipids, and Nucleic acids

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Proteins are considered polymers while Lipids are not because proteins are composed of monomeric subunits of amino acids whereas lipids do not have monomeric subunits.

Explanation:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur as they are found in many structures of living organisms- in proteins, carbohydrates, nucleic acids and lipids.

2. Carbon has the ability to form different large and complex structures because:

(I) its ability to catenate which is the ability to combine with one another to form straight, branched chain or ring compounds containing many carbon atoms.

(ii) carbon can form single, double and triple with itself and other life elements.

(iii) the relative stability of the covalent bonds formed by carbon.

3. Four groups of organic compounds found in living things are Carbohydrates, Proteins, Lipids, and Nucleic acids.

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Polymers are large molecular weight compounds built up from subunits called monomers.

Proteins are considered polymers because they are large molecular weight molecules composed of monomeric subunits of amino acids.

Lipids are not considered polymers because individually, they are not very large molecules and do not have monomeric subunits rather are composed of long fatty acids chains linked to a glycerol molecule.

Why is there more creatine kinase in dmd muscles compared to average muscles
Nastasia [14]

Answer:

Explanation:

Almost everyone with a neuromuscular disorder has had, or will have, a creatine kinase test. But what exactly is creatine kinase (CK), and why are its levels measured in neuromuscular diseases?

CK, also known as phosphocreatine kinase, or CPK, is a type of protein called an enzyme. It catalyzes, or "encourages," a biochemical reaction to occur. The normal function of CK in our cells is to add a phosphate group to creatine, turning it into the high-energy molecule phosphocreatine. Phosphocreatine is burned as a quick source of energy by our cells.

However, the normal function of CK isn't as relevant, in this case, as what happens to CK when muscle is damaged. During the process of muscle degeneration, muscle cells break open and their contents find their way into the bloodstream. Because most of the CK in the body normally exists in muscle, a rise in the amount of CK in the blood indicates that muscle damage has occurred, or is occurring.

To measure CK levels, a blood sample is taken and separated into fractions that contain cells and a fraction that doesn't — the serum. The amount of CK in the serum is reported in units (U) of enzyme activity per liter (L) of serum. In a healthy adult, the serum CK level varies with a number of factors (gender, race and activity), but normal range is 22 to 198 U/L (units per liter).

Higher amounts of serum CK can indicate muscle damage due to chronic disease or acute muscle injury. For this reason, if you're scheduled to have blood drawn for a CK test to diagnose a potential muscle disorder, you should limit your exercise to normal activities before the test.
