What is the purpose of having leak and gated channels for the neuron?
Answer:
Explanation:
The purpose of having leak and gated channels for the neuron is that the leak channels will allow the movement of sodium and potassium across the cell membrane downward from high concentration gradient to low concentration gradient. With the leakage of ions across the cell membrane, there is maintainence of a stable resting potential of cells.

The drug 2,4-dinitrophenol (DNP) destroys the proton gradient across the inner mitochondrial membrane. What would be the effect of incubating isolated mitochondria in a solution of DNP
Answer:
This question lacks options, options are:A) Oxygen would no longer be reduced to water. B) No ATP would be made during transport of electrons down the respiratory chain. C) Mitochondria would show a burst of increased ATP synthesis. D) Glycolysis would stop. E) Mitochondria would switch from glycolysis to fermentation.The correct answer is B)
Explanation:
The main mechanism of ATP production takes place in our mitochondria, which are cellular organelles, and this occurs when molecules of coenzymes or reduced prosthetic groups, coming from the process of catabolism of nutrients, are oxidized with molecular oxygen (which becomes in water), leading to the production of ATP. DNP works by increasing heat production in cells through a process known as decoupling. Dinitrophenol is an ionphoric compound that cuts mitochondrial ATP production circuits. This cessation of ATP production through the mitochondria leads to an increase in metabolic rate (as the substrate is used at a higher rate so that cytosolic ATP can sustain life) and subsequent weight loss.
Which of the following is an example of how the principle of beneficence can be applied to a study employing human subjects?
Answer:
Determining that the study has a maximization of benefits and a minimization of risks.
Explanation:
Choose a specific site for further study where eutrophication is a problem (such as Chesapeake Bay, the Baltic Sea, or the Gulf of Mexico). List some sources of nitrogen and/or phosphorous to the water body and describe some of the ecological problems due to eutrophication at this specific site.
Explanation:
Due to the commercial farming activities in the MidWest, fertilizers and pesticides are usually washed away by precipitation and drain into the Gulf of Mexico. These elements (mainly nitrogen and phosphorus) offer much nutrients for algae causing them to thrive into algae blooms. Bacteria then find ‘fodder’ in dead algae breaking them down for energy sources. The bacteria, mostly aerobic, take up most of the oxygen from the water as they thrive. This makes the waters of the Gulf hypoxic hence the other marine organisms such as fishes cannot thrive. Actually, the ecosystem dies and the region is recognized as a' dead zone'.

Answer: (Answers may vary.)
Sources of nitrogen and phosphorous in Chesapeake Bay include runoff from agriculture, air pollution from vehicles and power plants, and wastewater from sewage and industry. Ecological problems resulting from the eutrophication include blocking of sunlight to aquatic grasses, stressing fish and shellfish by depleting oxygen, and rising pH, which further stresses fish and makes them susceptible to parasites.

Sunspots are storms on the Earth's surface.
WHAT ARE SUNSPOTS?Sunspots are darker and cooler areas on the surface of the sun in a region called the photosphere.
Sunspots form on the surface of the sun due to strong magnetic field coming up from the sun core.
Sunspots appear visibly as dark spots compared to their surroundings. Therefore, sunspots are storms on the Earth's surface.

The energy used to pump hydrogen ions from the mitochondrial matrix across the inner membrane and into the intermembrane space is derived from:________
a. ATP hydrolysis
b. reactions in the electron transport chain
c. decreasing the pH in the mitochondrial matrix
d. splitting water to form oxygen and protons
Answer:
b. reactions in the electron transport chain
Explanation:
Oxidative phosphorylation, which is the process described in this question, is the third stage of cellular respiration which occurs in the MITOCHONDRION of eukaryotic cells. In this stage of oxidative phosphorylation, which encompasses electron transport chain (ETC) and chemiosmosis, ATP is synthesized.
The ATP is synthesized when protons (H+) move from the mitochondrial matrix into the intermembrane space, forming, a proton pump. The series of electron transfers (reactions) that occur in the complexes of the ETC provides the ENERGY to pump the protons/hydrogen ions out of the matrix, which creates the electrochemical gradient required for ATP synthesis with the help of ATP synthase.

Some amino acids are both glucogenic and ketogenic. Explain the difference between the two types and why some amino acids can be both g
Answer:
From the point of view of the type of molecule that is obtained after the degradation of the hydrocarbon skeleton, amino acids can be classified as: glucogenic and ketogenic. The main difference between glucogenic amino acids and ketogenic amino acids is that glucogenic amino acids can be converted to pyruvate or other glucose precursors, while ketogenic amino acids can be converted to acetyl CoA and acetoacetylCoA.
Explanation:
Glucogenic amino acids are amino acids that break down to pyruvate, alpha-ketoglutarate, succinyl Co-A, fumarate, and oxaloacetate and are so named because the synthesis of glucose from these molecules is feasible. Both pyruvate and the Krebs cycle intermediates noted above can be converted to phosphoenolpyruvate and subsequently glucose through gluconeogenesis.Ketogenic amino acids are the amino acids that generate acetyl-CoA or acetacetyl-CoA and are called by this name because they can cause ketone bodies. Since mammals lack the proper enzyme system, these compounds can never be used as precursors for glucose biosynthesis. Of the twenty universal amino acids, fourteen are purely glucogenic and two are purely ketogenic (leucine and lysine). The remaining four (isoleucine, phenylalanine, tryptophan and tyrosine) are glucogenic and ketogenic simultaneously since a part of the hydrocarbon skeleton originates precursors for the biosynthesis of glucose (pyruvate or Krebs cycle intermediates) and the other part acetyl-CoA or acetacetyl -CoA.
What happens on a cellular level during a organ rejection? Simplified.
Organ rejection takes place when your body is subjected to a new organ which is a foreign object and attacks it.
What do you mean by Graft rejection?Graft rejection may be defined as a process in which a transplant recipient's immune system attacks the transplanted organ or tissue.
Xenograft shows high rejection. This is because it involves the transplantation between genetically distinct members of different species.
The process of organ rejection is initiated by T cells which perform the role of the recognization of a transplanted organ.
If these T cells are activated, it may lead to organ rejection by undergoing clonal expansion, and differentiation of the effector cells, which together lead to the obliteration of the tissues.
Therefore, organ rejection takes place when your body is subjected to a new organ which is a foreign object, and attacks it.

Hormones that are secreted by one endocrine gland (i.e., anterior pituitary gland) and control the secretion of a hormone from another endocrine gland (i.e., adrenal gland) are generally called _____________ hormones.
A. tropic
B. glucocorticoid
C. activation
D. blood releasing
Answer:
A. tropic
Explanation:
Generally, hormones are chemical messengers that are secreted in a particular location and transported to another location to effect a physiological response. However, some set of hormones secreted by an endocrine gland functions in stimulating or regulating the secretion of other hormones by another endocrine gland. These group of hormones are called TROPIC HORMONES.
As stated in this question, the anterior pituitary gland, which is considered to be the "MASTER GLAND" secretes an hormone that controls the secretion of another hormone by adrenal gland. The hormone secreted by the PITUITARY GLAND is a TROPIC HORMONE. An example of tropic hormone is ADRENOCORTICOTROPIC HORMONE (ACTH) secreted by anterior pituitary gland.
