Gastrin secretes what?
pepsinogen (a precursor of pepsin) which helps humans digest, when activated by HCL.
Why are proteolytic enzymes produced in an inactive form?
Proteolytic enzymes will destroy the cells that produced them if they are produced in an active form. To protect the body's own cells these enzymes are secreted in an inactive form into the digestive tract and activated where they are needed.
Where is the lipase secreted and what does it digest fats into?
it is secreted by the pancrease.
What is adrenlinie?
Its a hormone secreted by adrenal glands. Its secreted during anxiety and excitement. It secreted when ACTH hormone is secreted by pituitary gland in brain. chemically, it is sterol(=steroid) i.e. Derivative of lipids.
Which substances are normally secreted into the distal tubule?
The ions that are secreted by the distal convoluted tubule are potassium ions. These are secreted to better control the levels of potassium and sodium.
What is a neurohormone?
A neurohormone is a hormone that is secreted and circulated by neurosecretory cells into the blood. It stimulates neural mechanisms when activated by neural stimuli.
What is the role of cytokine secreted by macrophage?
The cytokines that an activated macrophage secretes attract and activate other cells of the immune system.
What organ secretes carboxypeptidase?
Carboxypeptidase is secreted by Pancreas in inactive form (procarboxypeptidase) and is activated by trypsin. Carboxypeptidase is also secreted by small intestine as brush border enzyme. Reference: Human Anatomy and Physiology by Elaine N. Marieb
Gastrin secretes what?
pepsinogen (a precursor of pepsin) which helps humans digest, when activated by HCL.
What would be happen if HCL were not secreted in stomach?
Hydrochloric acid is secreted by the glands present on the stomach walls. It dissolves bits of food and creates an acidic medium. The acidic medium allows pepsinogen to be converted into pepsin. Pepsin plays an important role in the digestion of proteins. Therefore, if HCl were not secreted in the stomach, then pepsin would not be activated. This would affect protein digestion. A pH of about 1.8 is necessary for proteins to be digested. This pH is achieved by HCl.
Why are proteolytic enzymes produced in an inactive form?
Proteolytic enzymes will destroy the cells that produced them if they are produced in an active form. To protect the body's own cells these enzymes are secreted in an inactive form into the digestive tract and activated where they are needed.
What enzyme does hydrochloric acid activate?
Pepsin, in its inactive form it is known as pepsinogen. Lingual lipase, secreted by lingual glands in the tongue, are activated by the acidic environment of the stomach and thus work starts to work after food is swallowed.
Collagen and elastin are secreted by?
what is collagen secreted by
How does the duodenum get trypsinogen?
Precursor Trysinogen is an inactive enzyme which is converted to Trypsin by the enterokinase from the ileum. It's then released into the duodenum by secretin from the gut walls or mucosa cells of the duodenum.
Where is the lipase secreted and what does it digest fats into?
it is secreted by the pancrease.
What is adrenlinie?
Its a hormone secreted by adrenal glands. Its secreted during anxiety and excitement. It secreted when ACTH hormone is secreted by pituitary gland in brain. chemically, it is sterol(=steroid) i.e. Derivative of lipids.
Is human chorionic gonadotropin secreted by the adrenal cortex?
No. It is secreted by the placenta.
