Answer:
Cells vary greatly in shape These shapes are often related to the function they perform. like the disk shape of erythrocytes can absorb and transport oxygen due to increased surface area., the amoeboid shape of leukocytes allow them to squeeze through capillaries. etc.
Explanation:
Cells can be disc-like , polygonal, rectangular, cubopid thread like branched or even irregular. these are related to the functions that each cell performs.
Some examples showing relation between cell shape and function are as follows.:
- Human blood cells are circular and biconcave to transport oxygen.
- White blood cell are amoeboid to squeeze through thin capillaries.
- Nerve cells are long so that they can carry nerve impulse to a long distance very quickly.
- Guard cells of stomata are bean or dumbell shaped to open and close the stomata.
A phosphorus atom is not used as a monomer to make proteins
Answer:
The energy used for muscular cont ration is ATP(adenosine triphosphate) This is the energy currency produced in the mitochondrial during cellular respiration.
During muscles contraction.The ATPs is broken down to ADP and Pi.
This is the breakdown of energy rich bonds binding phosphate ions with ATP.The breakdown of the bonds produced -32kJper the 3 bonds in ATP. Therefore as each bond is broken, energy is produced for muscle contraction
It is an exergonic reaction with production of heat.
Thus ATP is used for muscle contraction.ADP is the intermediate of ATP when one Phosphate is removed during the breakdown.
Thus the sequence is Adenosine triphosphate (3 phosphate) to Adenosine diphosphate(2 phosphate) to Adenosine monophosphate (1 phosphate)
Each bond breakin gives equal energy of -32kJpermol.
