A pituitary adenoma that secretes excessive amounts of growth hormone is likely to cause decreased Group of answer choices
1. plasma concentration of IGF-1
2. uptake of amino acids by muscle
3. plasma concentration of free fatty acids
4. tolerance to a glucose load
5. synthesis of milk

Plasma concentration of IGF-1 is the right answer.

Explanation:

When pituitary gland produced excessive amount of Growth hormones is called Acromegaly.

The main cause of acromegaly is over producing Growth Hormones(GH)by the pituitary.when GH secreted into blood it influenced liver to produced insulin -like-growth factor-I(IGF-1).Then IGF-1 stimulates the growth of bones and tissue.

When pituitary produced large amount of GH it leads to overproduction of IGF-1.excessive of IGF-1  Cause abnormal growth of soft tissue and skeleton.

explanation:

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
