The molecule shown below is a molecule that is generally termed as the energy currency molecule of the cell, and that is ATP.
The components of it include:
1. Adenine nitrogenous base, the far left
2.Ribose, sugar the same sugar found in RNA molecules, middle.
3. Triphosphate - 3 covalently bound phosphate groups ready to split apart as they don't typically like being bonded in that manner, due to charges on phosphate, being negatively charged.
Answer: Possible consequences of climate change to species that have a narrow temperature tolerance range are extinction, change in migratory patterns, and decreased population.
1. Regulation of glucose blood levels is an example of negative feedback mechanism.
Negative feedback mechanism is a control mechanism involved in homeostasis maintain, in this case maintenance of glucose blood levels in normal range.
Negative feedback mechanism contains sensory system that detects the changes, control system that responds to change and activates mechanisms of effector system that reverse the changes in order to restore conditions to their normal levels.
• Pancreatic cells-sensors
• Insulin-control system
• Body cells- effector cells
2. Blood glucose levels change throughout the day because of the food consumption, but in healthy individuals levels of glucose are successfully regulated via the mechanism of hormones such as insulin and glucagon in a process called glucose blood regulation.
This tight regulation of pancreatic hormones is referred to as glucose homeostasis. Insulin lowers blood sugar and glucagon raises it.
3. If the beta cells are destroyed by an autoimmune disease (immune system attacks its own cells), there would be no insulin release, and consequently, the glucose blood levels would be increased.
Diabetes type I is a metabolic disorder caused by the destruction of insulin-producing pancreatic beta cells.
Olafactory bulbs because it has to do with nerve signals and neurons. Brain because it is the center of the nervous system and the closest to the nose in terms of the nervous system.
