The cytoplasmic fragments of the megakaryocytes constitute the platelets, this fragments simultaneously into thousands of new platelet cells, these morphological changes are known as proplatelets.

<h3>What are proplatelets?</h3>

They are cytoplasmic protrusions from which platelets or fragments are going to be detached that end up maturing in the circulation.

<h3>Characteristics of proplatelets</h3>

  • Platelets are formed from the fragmentation of giant cells, which emit cytoplasmic protrusions.

  • Each megakaryocyte has about 6 proplatelets, and each proplatelet houses about 8,000 platelets, these "bags" full of platelets enter the bloodstream where they break, releasing them.

Therefore, we can conclude that the megakaryocytes form the future platelets, these platelets are grouped in cytoplasmic portions, called proplatelets.

Zigmanuir [339]

Answer:

The correct answer is : C .It will decrease ATP production because fewer protons will be able flow down through ATP synthase.

Explanation:

  • Oxidative Phosphorylation is a process which involves two steps:  
  1. Transport of electrons from the reduced compounds like NADH (Nicotinamide adenine dinucleotide hydrogen) and FADH₂ (Flavin adenine dinucleotide dihydrogen) through the electron transport complexes, located in the inner mitochondrial membrane, to oxygen for the generation of water molecules.
  2. Synthesis of ATP or adenosine triphosphate from ADP or adenosine diphosphate and inorganic phosphate by an enzyme called ATP synthase which is located in the inner mitochondrial membrane. This enzyme harnesses energy by carrying protons from the inter-membrane space into the mitochondrial matrix and in the process produces ATP.
  • Oxidative phosphorylation takes place in the mitochondria, especially involving the inter membrane space, inner membrane and mitochondrial matrix
  • During the transport of electrons through the protein complexes (I, II, III, IV) of the electron transport chain a proton gradient is generated across the inner mitochondrial membrane.
  • The proton gradient is such that the concentration of protons is more in the inter-membrane space and less in the matrix of the mitochondria.
  • This proton gradient provides the energy to the ATP synthase for the synthesis of ATP.
  • Dinitrophenol is responsible for making the inner mitochondrial membrane permeable to protons. As a result protons can directly diffuse through the inner mitochondrial membrane from the inter-membrane space into the mitochondrial matrix equalising the concentration of protons across the inner mitochondrial membrane. This causes distortion in the proton gradient.  Hence, protons are no longer available for the ATP synthase to operate and synthesise ATP.

IrinaK [193]

Answer:

The correct answer is "The eggs must have internal membranes".

Explanation:

Amniotes are animals that have adapted to reproduce putting eggs on land (reptiles, birds or mammals). The eggs of amniotes have internal membranes that let gases but not water pass through. This characteristics allows the embryo to breath inside the egg, and allow the egg to not dry out on land. Therefore, the eggs of the new species of animal must have internal membranes in order to allow its reproduction on land.
