Answer:
If a large molecule need to move against the concentration gradient the struc of an energy rich compound such as Adenosine tri phosphate or ATP is need to be used.
Explanation:
ATP provides energy to carry out the uphill transport of molecule across the plasma membrane by the helps of specific ion channel.Uphill transport is a type of membrane transport process in which a molecule is being transported against its concentration gradient that means the molecule is moving from low concentration region to high concentration region.
In general this type of transport is Thermodynamically unfavorable which is made favorable by the energy derived from the hydrolysis of ATP .
Answer:
The False statement is
Exchange gases with blood
Explanation:
Gas exchange occurs at the alveolar level which is part of the lower respiratory track
Answer: Option A
Explanation:
Kinesin -1 is the major anterograde motor which helps in the transportation along micro tubules. This is important for the proper transport of the mitochondria, Golgi derived vesicles, endoplasmic reticulum tubulin, mRNA and intermediate filament sub units.
It moves along the micro tubules and for this task it gets energy from the adenosine triphosphate.
The heavy chain of KInesin 1 is made of globular head via short flexible neck and has a light chain as well which ends in the carboxy terminal.
