What energy yield (in molecules of ATPATP per molecule of monosaccharide) would you predict for the bacterial catabolism of raff
Katena32 [7]

Answer:

The correct answer is 2.67 ATP per molecule.

Explanation:

With the help of sucrose, it comes to known that the dissociation of a sugar-sugar bond generates one phosphorylated monosaccharide. Therefore, raffinose, which is a trisaccharide exhibits bonds of two sugar-sugar molecules. Post dissociation, they will generate one regular monosaccharide and two phosphorylated monosaccharides.  

There will be the generation of net ATPs by each phosphorylated monosaccharide as they are already phosphorylated. While the regular monosaccharide, which is first needed to get phosphorylated will only produce two ATPs. Thus, a total of 8 ATPs will be produced by one molecule of raffinose. After dividing by three monosaccharides, the molecule will produce 8/3 = 2.67 ATPs per monosaccharide.

Name a hormone secreted by the thyroid gland that acts to lower blood calcium
Sergio [31]

Answer:

Thyrocalcitonin or TCT

Explanation:

Thyrocalcitonin or TCT is a non-iodinated calcium lowering hormone. It is originating from the parafollicular cells or C cells (C for calcium).  

The thyroid gland consists of follicles of cuboidal epithelial cells. These cuboidal cells have a nucleus at the base. These are principal cells responsible for the synthesis of thyroid hormones.

 In between these follicular cells, other high cuboidal cells are present, known as parafollicular cells / C cells. These cells synthesise the hormone TCT. When there is high levels of calcium ions in the serum, TCT will release. This lowers the high level of calcium ions in the blood and plasma to normal level. This is done due to the deposition of calcium in the bone.

How would the introduction of a predator species affect the stability of an ecosystem
ss7ja [257]

The predator species keeps the prey species under control. Without predators, prey animals would over populate.

Autonomic dysreflexia is characterized by a. hypotension and shock. b. hypertension and bradycardia. c. pallor and vasoconstrict
omeli [17]

Answer:

B) hypertension and bradycardia.

Explanation:

Autonomic dysreflexia is a syndrome which is characterised by the sudden rise in the blood pressure of the human. The disease is common in the people with a higher level of spinal cord injuries above the T6 level.

The condition occurs when some external stimuli like pain or irritant activate the involuntary response in the body which cause the blood pressure to rise (hypertension). This leads to the slowdown of the heartbeat (bradycardia) to restore the blood pressure but the body cannot restore the blood pressure due to the damage in the spinal cord.

Thus, Option-B is the correct answer.
