Answer:

systemic lupus erythematosus

Explanation:

Systemic lupus erythematosus (SLE or just lupus) is a chronic inflammatory disease of autoimmune origin, the symptoms of which may appear in various organs slowly and progressively (in months) or more rapidly (in weeks) and vary with phases of activity and remission. Because it is a disease of the immune system, which is responsible for producing antibodies and organizing inflammation mechanisms in all organs, when a person has SLE they may have different types symptoms and various body locations. Some symptoms are general such as fever, weight loss, loss of appetite, weakness and discouragement. Others, specific to each organ such as joint pain, skin blemishes, pleural inflammation, hypertension, and / or kidney problems.

The main cause of this disease is the imbalance in the production of antibodies that react with proteins in the body itself and cause inflammation in various organs such as the skin, mucous membranes, pleura and lungs, joints, kidneys, etc.). Thus, we understand that the type of symptom a person develops depends on the type of autoantibody the person has, and that as the development of each antibody relates to the genetic characteristics of each person, each person with lupus tends to have clinical manifestations. specific and very personal (symptoms).

Autoantibodies are antibodies directed to the body's own cells and tissues. Normally, the immune system differentiates the body's own proteins from foreign proteins, forming antibodies only against those identified as potentially dangerous.

Which statement describes how enzymes and substrates are related? The enzyme influences the speed of change from substrate to pr
azamat

Correct answer: A). The enzyme influences the speed of change from substrate to product

The enzymes are the biological catalyst that speed up the rate of chemical reactions by decreasing the activation energy of the reaction pathway.

They increase the speed of change of substrate to the product and it remains unchanged in the reaction. Hence, it can be used again and again.

Enzymes are highly specific in nature, only a specific substrate binds to the enzyme's active site. Hence, a particular enzyme is required to catalyze a reaction.
