Homeostasis
The ability of a system or organism to maintain equilibrium and stability while adapting to environmental disturbances.
What is Homeostasis?
Chemical substances that act as messenger molecules in the body.
What are Hormones?
The hormones that are secreted by the pancreas.
What is Insulin and Glucagon?
This gland, located at the base of the brain, plays a crucial role in regulating the body's homeostasis by secreting hormones that control various functions.
What is the Pituitary Gland?
The name of the polysaccharide that glucose is converted for storage
What is glycogen
These are responsive to particular stimuli or alterations in their surroundings.
What are Receptors?
The hormone that stimulates the pituitary gland to produce thyroid-stimulating hormones.
What is thyrotropin-releasing hormone?
The two enzymes present in the liver that aid in the conversion of glucose to glycogen.
What is Glucokinase and Glycogen synthase?
Hormones are released into the bloodstream in response to this
What is stimuli
Second step of fruit ripening with the effect of ethylene and the mechanism it creates.
What are autocatalytic production and positive feedback loop
The mechanism that helps to regulate hormone levels by inhibiting further hormone release when a certain threshold is reached.
What is Negative Feedback?
Ductless gland.
What is the Endocrine gland?
Inhibits glycogen breakdown.
What is Insulin?
Four changes that occur in a ripening fruit
What are colour change, softening of texture, increase in sweetness and production of a new aromatic compounds.
Name six non-steroid Hormones
What are growth hormone (GH), Antidiuretic Hormone (ADH), Adrenaline (Epinephrine), Oxytocin, Insulin and Glucagon
The components of a biological system that carry out responses to a stimulus.
Plant hormone that is viral to fruit ripening
What is Ethylene
The conversion of Lipids and Amino acids to glucose.
What is Gluconeogenesis?
Change in colour of ripe fruits are as a result of a breaking down of this chemical.
What is chlorophyll
The set point of blood glucose concentration
The target value for Homeostasis.
What is a Set Point?
Involves the activation of intracellular pathways, which can lead to changes in gene expressions.
What is Signal Transduction
The cell that secretes insulin in response rise in blood glucose level.
What are 𝛃 - cells?
In the commerical uses of ethylene to ripen fruits, the process can be hastened or slowed by two things respectively.
What are increasing temperature and refrigerating the fruits.
Name 4 bodily parameters that homeostasis helps to regulate
What are temperature, pH, blood sugar levels and water balance.
