Substances effect: partially blocks (H+)/pyruvate symporter, interfering with the transport of pyruvate into the mitochondria. W

ill this make the body lose or gain weight?
Biology
1 answer:
MatroZZZ [7]3 years ago
3 0

Answer:

It will lose weight

Explanation:

The pyruvate is the product formed by the process of glycolysis by the breakdown of the glucose-mediated by enzymes.

The process of glycolysis take place in the cytosol therefore for further processing or stages of respiration, the pyruvate has to enter the mitochondria which occur through the (H+)/pyruvate symporter.

In the given question condition, if the symporter is blocked then the pyruvate will not enter into the mitochondria as a result of which less ATP will be produced. So the body will use some other sources which can form the pyruvate which can easily enter the mitochondria.

Therefore, the body will begin to lose weight.

The site where the more movable end of a muscle attaches is the question 3 options: origin insertion belly fascicle
Lilit [14]
The correct answer is the insertion.
<span>Insertion is the attachment site of the muscle end that does move when the muscle contracts. On the other hand, the origin is the attachment site that does not move during contraction (end of the muscle is fixed).</span>

Which of the following statement(s) is/are true regarding the adrenal glands' relationship with the autonomic nervous system?
Studentka2010 [4]

Answer:

The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:

a. The adrenal cortex is an extension of the parasympathetic nervous system.

c. The adrenal glands are strictly nerve tissue.

d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.

e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.

Explanation:

The  levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord.  Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs.  This alert serves as a warning signal and defense system.  The purpose is to maintain homeostasis.

Read each description below and determine whether or not it describes a function or property of cerebrospinal fluid. Identify wh
Ostrovityanka [42]

Answer:

Produced by the choroid plexus -T.This is the major secretion site.It is also produced in smaller quantities in the interstitial compartment.

Blocks blood toxins from brain tissue-F, that is the job of  the blood brain barrier(BBB).

Supplies oxygen to the brain tissue-T.This gas is dissolved  in the CSF together with CO2 for distribution among nervous tissues by the CSF

Maintains the concentration of glycine surrounding the brain-T

Found in the ventricles of the heart and brain-False,it does not reach the heart ventricles.This are occupied by blood.

Prevents concussions-T

Produces antibodies in response to antigen exposure in the brain tissue-False.These are produced by the B-cells, not by in the CSF,based on the  specif antigen stimulation.

Effectively decreases the brain's weight-T It reduces the weight of the brain.This is done by the buoyancy it provided for the brain.

Compared to levels in the blood plasma, the CSF is higher in glucose-F.This is wrong, the glucose of the blood plasma is higher.But equal sodium ion,more chloride in CSF, and less protein.It s levels is a relefection of blood glucose.Although it may lag 2-4hrs in the CSF.

It prevents concussion,(T)and and the contraction of cardiac muscles propels its movement(T).
