Answer: The biconcave shape of erthrocytes is as a result of PERIPHERAL PROTEINS anchored to the inner surface of their plasma membrane.
Explanation:
Erthrocytes or red blood cells are cells produced by the bone marrow which transport oxygenated blood through out the body. The biconcave shape of red blood cells is as a result of peripheral proteins anchored to the inner surface of their membrane plasma.
The biconcave shape increases the flexibility of erthrocytes which allow the red blood cells to travel through capillaries with tiny size of diameter, give the red blood cells large surface area and increase their abilities to transport oxygen.
peripheral proteins anchored to the inner surface of their plasma membranes
Explanation:
The anchored of peripheral proteins to the inner surface of RBC plasma membrane which makes them thick or plump at the peripheral and thin at the center, is an adaptive feature of RBC for increasing the surface area to volume ratio of RBC for transport of maximum molecules of oxygen by binding with haemoglobin( which occupies the centre,)
The biconcave nature also ensure passage of RBC by squeezing through tight and narrow capillaries to reach needed tissues.
It is in the mitochondria that cellular respiration takes place. Therefore, the more mitochondria, the more ATP produced as a result of cellular respiration. More ATP = more energy. Muscle cells need more energy, so they contain more mitochondria.
Hydrolysis reactions can be the reverse of a condensation reaction in which two molecules join into a larger one and eject a water molecule. Thus hydrolysis adds water to break down, whereas condensation builds up by removing water.
