The integration center of the body
What is the brain and spinal cord
The three plasma proteins and functions for each one.
what is :
a. Albumin: accounts of 60-80%; influences osmotic pressure (draws water from interstitial fluid into capillaries); maintains blood volume and pressure
b. Globulins: alpha and beta (transport lipid-soluble molecules); gamma (antibodies)
c. Fibrinogen: functions in clotting (inactive at first; fibrin → fibrinogen)
The minimum water that we much excrete everyday
What is obligatory water loss?
Type of hormone needs a receptor to pass the plasma membrane?
What are polar hormones?
Thymine only exists in DNA, so when you see _____ you would be able to identify the strand as RNA.
What is uracil?
During this period, voltage gated channels close. This ensures unilateral movement, so the action potential continues to move forward.
What is a refractory period?
This shape of RBC's helps them ____.
What is biconcave? What is increasing surface area to carry O2?
The hormone produced by the kidneys to help stimulate the production of RBC's in our body.. the RBC production will be stimulated in the red bone marrow.
What is erythropoietin?
The two hormones are stored and released in the posterior pituitary?
What are oxytocin and ADH?
Transcribe an RNA strand for this DNA strand:
C, G, T, A
What is:
G, C, A, U
The purpose of nodes of ranvier is to facilitate _______, speeding up conduction rates.
In ____ circulation, these arteries carry deoxygenated blood to the lungs in order to be oxygenated.
capillaries
This is where ADH is produced
What is the hypothalamus
When a substrate and enzyme bind to form a _____. There are coenzymes & _______ that may bind to the enzyme to aid in it's function.
What is an active site. What is a cofactor?
What neurotransmitter do somatic motor units release onto the sarcolemma?
What is acetylcholine?
The 3 ways that carbon dioxide is released from the blood.
1.dissolving in the plasma
2.binding to hemoglobin
3. as a bicarbonate ion
These digestive cells are essential to protecting our stomach from HCL.
What are goblet cells.
Regulates the balance of water and salts in the body
When NAD turns into NADH it has been _____. When NAD turns into NAD+, it has been _____.
What is reduced? What is oxidized?
Explain what happens in order for cross-bridging to occur & Ca2+ significance.
Ca2+ would need to bind to ____ .. this causes it to change shape and move _____ in order for the _____ heads to attach to ____. Thus forming a cross bridge.
What is:
-Troponin
-Tropomyosin
-Myosin
-Actin
This enzyme catalyzes the reaction of CO2 --> bicarbonate ion.
Extra points: What is the equation?
What is carbonic anhydrase
What is
CO2 + H20 = (H2CO3) carbonic acid + carbonic anhydrase enzyme = HCO3- (bicarbonate)
This enzyme is ____ and is used in digestion specifically for breaking down proteins.
What is the inactive enzyme pepsinogen?
The final product from the target organ regulates secretion of anterior pituitary hormones.
Anterior Pituitary Negative Feedback Control
