What is the function of cellular membrane?
It is to protect the inner workings of a cell. It is a soft and thick tissue that is composed on phopholipids.
What do the phospholipids do in the cell membrane?
The phospholipids act as protecter for the membrane. It has polar (hydrophilic) heads and non-polar (hydrophobic) tails. This makes it so that only non-polar compounds can pass through the phospholipids and polar compounds must pass through the channel proteins.
What is the importance of the R group.
1.Controls Plasmid Compatibility
2.Affects Plasmid Maintenance and Segregation
3.Defines Plasmid Types
What does insulin do to your blood pressure?
When blood levels are too high your body will not be able to stay in a healthy state. Insulin will enter the blood and raise your glucose uptake. This results in a lower blood pressure.
Where do ADH hormones come from
They secrete from the pancrease
What is the role of ADH hormones?
hormone that plays a crucial role in regulating the body’s water balance, blood pressure, and blood volume. It is produced by the hypothalamus and stored and released by the posterior pituitary gland.
What is the role of Glucagon
When your blood sugar is too low glucagon will enter the blood stream and Stimulates glycogenolysis resulting in a higher blood pressure.
Give an example of what ADH does to help your body.
If your body is dehydrated it will limit your bladder secretion.
What is ATP role in the body
It is an energy source in your body. An example of this is the Krebs cycle and the Calvin cycle. It can take and donate a Phosphate atom when needed.
What are nephrons?
Nephrons are the functional units of the kidneys, responsible for filtering blood, removing waste, and maintaining the body’s fluid and electrolyte balance. Each kidney contains about 1 million nephrons, which work together to produce urine and regulate key physiological processes.
What are axons?
Axons are long, slender projections of nerve cells that transmit electrical signals (action potentials) from the cell body of the neuron to other neurons, muscles, or glands. They are essential for communication within the nervous system and for controlling various bodily functions.
What are dendrits
Dendrites are the branched, tree-like extensions of a neuron that receive incoming signals (information) from other neurons or sensory stimuli and transmit them toward the cell body (soma). They play a critical role in the communication and integration of neural signals in the nervous system.
What are neurons
Neurons are the fundamental building blocks of the nervous system. They are specialized cells responsible for transmitting information throughout the body via electrical and chemical signals. Neurons are essential for all bodily functions, including sensory perception, motor control, and higher cognitive processes like learning, memory, and decision-making.
