Cell Biology (cytology)

What is happening in cytoplasm?


Wiki User

Cytoplasm is the fluid within the cell, but it is very glutinous due to the presence of multitudinous proteins, sugars, amino acids and other organic compounds, not to mention billions of ions like K+ and Na+. The processes undergone in the cytoplasm are uncountable. Glycolysis the precursor of the energy-giving reactions of aerobic respiration occur in the cytoplasm. Ribosomes are drifting about as are tRNA molecules with attached amino acids - and all this for translation (production of protein) which can occur free in the cytoplasm or attached to the granular endoplasmic reticulum. Depending on the type of cell, Na+ and K+ cations are drifting endlessly across the plasmalemma into and out of the cytoplasm, all to undergo the processes of the polarisation and depolarisation of membranes, functions essential to the cardiovascular and nervous systems. In erythrocytes, a small fraction of the blood's CO2 is transported in the cytoplasm. And as I said the rest of the chemical occurrences in cytoplasm are innumerable.
