<h3>What is skin?</h3>

Skin is considered a protective layer that covers all your body. This layer is essential for many reasons.

<h3>What are the functions of skin?</h3>

The main functions of this organ include:

  • Regulating temperature.
  • Producing Vitamin D after sun exposure.
  • Protecting other structures including inner tissues and organs.

However, it is not a function of the skin to produce new blood cells, this process occurs inside the bones in an area known as brown marrow rather than in the skin.

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.

What cause water to be a polar molecule
stich3 [128]
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.
