Answer:

Regeneration of ATP is an endergonic reaction and is coupled with an exergonic reaction.

ATP hydrolysis is an exergonic reaction and provides energy for other endergonic reactions.

Explanation:

Phosphorylation of ADP into ATP is an endergonic reaction while ATP hydrolysis into ADP and inorganic phosphate is an exergonic reaction.

The exergonic reactions are the ones that release energy. The released energy can drive the endergonic phosphorylation of ADP into ATP.

The endergonic reactions are the ones that need the input of energy to occur. These reactions are often coupled with ATP hydrolysis as ATP hydrolysis releases energy.

Therefore, endergonic reactions use ATPs while exergonic reactions release energy to regenerate ATPs.

Answer:

Sponges use choanocytes or flagellated channels to get nutrients from the feeding cells to other parts of their body.

Explanation:

Sponges are marine animals with a sac-shaped body. The epidermis is composed of polygonal flat cells called pinacocytes and pores protected by porocytes. Under the epidermis, there is a protein matrix called mesenchyme, which is composed of spicules and amibocytes. By the interior side of the sponge, there are the choanocytes. These are ovoid cells that can be shaping the spongocoele (internal cavity of the sponge), with an extreme attached to the mesenchyme and the other extreme projected to the spongocoele, or can be grouped in spaces called flagellated channels.

These animals depend on water to get oxygen and food to the inside of the sac and take excrements and reproductive cells to the outside. Sponges feed on small detritus particles and suspending organisms that get near the animal by water streams produced by choanocytes.

Particle size is essential. Only the small ones can get through the flagellated channels, where they get stuck to the choanocytes and are encapsulated by the cells. If the choanocytes are too small, the particle is transferred to the amibocytes for digestion. These last ones also act as food storages. Excrement products are dragged by a water stream.

Answer:

The neuro cognitive disorder of blood flow to the brain is called as dementia.

Explanation:

When mental function decreases due to mental diseases,the term is called dementia in medical terminology.

There are several causes of dementia are-

Brain injury which is caused by trauma.
Intra cerebral hemorrhage,blood clot in the brain
Breathing problem like hypoxia.
Cardiovascular problems like TIA, Stroke,heart infection etc.
Alzheimer disease,Huntington disease,HIV,any injury in brain.
Pick disease etc
