Biological Factors Affecting Biological Organisms
Cell signalling is the communication between cells and between the cell and their environment. This connection is needed in order for them to function. For example cell signalling controls specialised cell functions such as contraction of muscle cells for movement. Development of cells from stem cells into specialised requires cell signalling to complete differentiation into leukocytes, erythrocytes, muscle cells etc. However defects in cell signalling in development it can lead to birth defects. Lastly another function of cell signalling is response to environmental stimuli. An exemplar of this is the physiological response of sweating in flight or fight situation which requires cell to communicate with neurotransmitters and adrenaline to start the response. Within cell signalling it involves many processes, some of which crosstalk. Allowing pathways to interact forming networks and create signalling pathway. Substances like adrenaline, insulin, neurotransmitter acetylcholine …show more content…
These are intracellular signalling molecules that amplify the signal throughout the cell using signal induction pathways. [9]
Diacylgycerol (DAG) is a second messenger its production is activated by enzyme phospholipase, which is a protein in the membrane of the cell. The production of DAG is a result of neurotransmitters like GABA binding to G protein receptors which activates phospholipase forming second messengers DAG and inositol-1, 4, 5-triphosphate (IP3). The IP3 activates Ca2+ which is another second messenger. DAG and Ca2+ together activate the production of protein kinase C to phosphorylate other proteins in cell this results in growth and differentiation in the cell. Second messengers may be involved in more than one signalling pathway. [10]
Below figure 1B shows a pathway for second messengers DAG, IP3 and Ca2+. Figure 1B [11]

1020 Words | 5 PagesThe supply of glucose to the brain and immune system is important as competitors constantly rely on instantaneous decision making to ensure they make effective strategic moves. Glucagon is the hormone which ultimately increases blood glucose concentration by breaking down stored glycogen in muscle and fat cells, increasing the breakdown of fats and increasing liver glucose production. Each of these effects lead to an increased amount of glucose present in the bloodstream, meaning more energy for body cells. When the level of glucose in the bloodstream drops, more glucose is required in order to provide ATP for energy. The secretion of insulin by beta cells is inhibited

Ap Biology Case Study
896 Words | 4 PagesThe main problem that would occur is the plants would not be able to conduct photosynthesis at a rate that can support them and they would start to die off. When the plants die off the organisms that eat the plants wont have any food so they will die off and so on. The temperature of the earth would most likely drop due to the lack of sunlight exposure as well. An earthworm wouldn’t suffer a huge amount until the bacteria started to die off due to the overall imbalance of the food chain, earthworms would definitely survive the longest because their food source would be the last to die off. The sharks also would not be affected for a while because it would take time for the algae to die off from lack of sunlight and cause a chain reaction of

The pancreas produces a hormone called insulin, a chemical messenger for the entry of glucose into the cells. As the blood glucose levels rise after a meal insulin is released into the bloodstream and sets process into motion to trigger glucose to enter into the cells. When the glucose enters into the cells the amount of glucose in the bloodstream

It consists of many parts, most notably lymph nodes, white blood cells, and lymphocytes.. When an infection is spotted, white blood cells swarm it and attack it. If the white blood cells cannot handle the infection, lymph nodes create lymphocytes, which attack the infection with renewed force, and help prevent infection in the future (Human Biology 149).
Biological Factors In Lord Of The Flies Essay
639 Words | 3 PagesWhen it comes to the novel, Lord of the Flies, some of us will readily agree that the boys’ immoral and savage acts exposed at the end of the novel, demonstrates the evil that lives naturally within humankind. Where this agreement usually ends, however, is on the question of was the cause for the boys’ immoral and savage conducts a biological or an environmental factor. Whereas some are convinced that biological factors are to blame, others maintain that the situation or the environment is to blame for their behavior. In my own view, both factors are to blame for the boys’ immoral and savage behavior, but the environment the boys’ where force to live had the most impact on their actions. Being deserted on an unknown island can cause any individual to experience a variety of emotions all at once; from fear, to anger, and then excitement.

As the human civilization moved forward toward agriculture the diets of humans also changed. Depending on where the humans originated would give insight to how much of their diet was starch based. My family’s geographic origins are from China. Thus knowing that the country has a high starch based diet, we would suggest that I would have a high amylase production.
What Is The Effect Of Pollution On Marine Life

It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
