lyudmila [28]

Answer:

Overproduction can cause many diseases like

Proteinuria and  Amyloidosis

Underproduction may also leads to many problems like

Celiac disease and Congestive heart failure

Production of proteins at incorrect times may lead to severe conditions like

Ulcer

Explanation:

Overproduction of Proteins:

Proteinuria

This is the condition caused by the overproduction of proteins within the body. The urine of Proteinuria patients contains an abnormal amount of protein. This is linked with kidney disease. Filtration damage in kidneys causes the release of proteins like albumin leak in the urine.

Amyloidosis

This is the disease in which amyloid protein in high concentration get deposited in the organs, which causes these organs to malfunction. Organs which are affected by this condition are kidneys, heart, spleen, liver, nervous system, intestines or stomach.

The Underproduction of Proteins:

Low level of protein production can lead to many conditions such as

Celiac disease:

This is the disease in which the patient is intolerant to gluten protein which can damage the small intestine by activating the immune response.

Congestive heart failure:

This is the condition in which heart-pumping power becomes weak due to the underproduction of heart muscles.

Production of proteins at incorrect times:

Incorrect timing of the proteins may lead to severe conditions like

Ulcer:

The Stomach produces enzymes pepsin and HCl which cause the food to digest. If this protein produces at the wrong time with regular interval it may cause Ulcer.
