Answer:
Both facilitated diffusion and active transport are selective processes. Only selective molecules are allowed to cross the membrane. They utilize carrier proteins to move across the membrane.
Explanation:
Diffusion is the process by which molecules move across a membrane respective of the concentration gradient. The plasma membrane is a <em>selectively permeable membrane</em> which allows specific molecules to move across the concentration gradient.
Molecules migrate from a region of higher concentration to a lower concentration in case of diffusion. It can be classified into simple diffusion and facilitated diffusion. These are examples of <em>passive transport</em>.
In facilitated diffusion molecules move across the concentration gradient with the help of <em>carrier proteins or channel proteins</em>. The carrier proteins bind to the molecule which has to be transported and change conformation to allow it to cross the membrane. For example glucose molecule is carried across through <em>GLUT transporter</em>. <em>Channel proteins</em> open a channel inside the membrane and molecules get transported across the gradient.
Active transport carries molecules against the concentration gradient with the assist of energy. ATP hydrolysis is utilized to generate energy. As a result of active transport, the molecules are aggregated on one side of the membrane.

Answer:
If 10 glucose molecules are broken down, 320 ATP molecules will be generated during the electron transport chain.
Explanation:
In the electron transport chain, high energy electrons travel across a series of proteins embedded in the inner mitochondrial membrane, releasing energy in the process.Hydrogen is pumped from the matrix into the intermembrane space, therefore an hydrogen ion gradient is formed across the inner membrane.These proton are then pumped back into the mitochondrial membrane where the synthesis of ATP from ATP synthase takes place.
In the electron transport chain, a total of 32 ATPs are generated per glucose molecule.
so if 10 glucose molecules are broken down:
1 glucose ⇒ 32 ATPs
10 glucose ⇒ 10*32
320 ATP molecules
Bee sting in a child is really a
concern than with the adult because this would cause anaphylaxis, which is a
fatal reaction of severe allergy. The effects are swelling, sweating, and pain,
difficulty in breathing, dizziness and shock. In this life-threatening
scenario, infant really needs immediate care for their immune system and other
body organs are not yet fully develop to fight for the allergic reaction.
