Do autotrophs need to carry out cellular respiration?
yawa3891 [41]
Plants do carry out cellular respiration
They use it to convert glucose, a product from photosynthesis, into ATP, the energy carrying molecule

Btw plants and animals carry out cellular respiration
ONLY PLANTS carry out photosynthesis because they make their own food but they still need to convert it into energy

suppopse you were going to deisgn a system for the rapid diffusion of oxygen across a phosphlipid bilayer. according to fick's l
Llana [10]

Answer:

According to Fick's law, the rate of diffusion of any substance across any barrier is<u> directly proportional to the surface area of the membrane or any layer exposed. and the concentration of the diffusing substance available, but the rate is inversely proportional to the diffusion distance available.</u>

<u />

Thus the rate at which oxygen will move across the phospholipid  bilayer will depend on the concentration or amount  per mole  of the oxygen molecule hitting the phopholipid at  a prticular time and how permeable the phospholipd layer is to oxygen molecules, but the rate of its  movement across will be reduced as the distance between the phosphoslipid bilayer and the diffusing molecules  increases.

Therefore, the concentration of oxygen should be maximised, the surface area of the phospholipid  bilayer should also be maximized. the distances between the phopholipid and the  vessel containing the diffusing oxygen molecules should be drastically reduced. With this Fick's law  has been applied , and therefore maximum oxygen molecules can diffuse across.
