Question
1. When the mitochondrial uncoupling protein UCP1 is activated in __________ [ Select ] ["cerebral", "yellow", "brown"] adipose tissue, it leads to the generation of additional _______________ [ Select ] ["adipose tissue", "fat", "heat"] .
2. When the ATP/ADP ratio in hepatic cells is high, then _______
ATP production is inhibited
3. Insulin is a hormone that ___________ [ Select ] ["decreases", "remains the same", "increases"] blood glucose concentration, and other hormones have the opposite effect. This is an example of __________ [ Select ] ["antagonistic", "agonistic", "protagonistic"] effectors maintaining homeostasis.
- glycogen is synthesizedExplanation / Answer
1. Brown, heat
UCP1(uncoupling protein1) present in brown adipose tissue in the inner mitochondrial membrane.it is regulate the proton channel.UCP1 capable to dissipate the proton grediant.The energy lost during dissipate the proton grediant by UCP1.this energy loss generate the heat.
2. Respiratory enzymes in the cell are inhibited. because high ratio of ATP/ADP suppress the glycolysis by inhibiting the respiratory enzymes.
3.decreases, antagonistic
When blood glucose concentration is high so beta cell of pancreas secrete insulin.
Insulin increases uptake of glucose by body cells thus decreases the blood sugar level.
Some other hormones like glucagon have opposite effect to insulin and secreted when blood sugar level is low.They are called antagonistic to insulin and maintain the blood sugar level .thus they maintaining homeostasis.
