In a dismissal that underlines his firm rejection of religious comforts, Britain's most eminent scientist said there was nothing beyond the moment when the brain flickers for the final time.
How are the tails and heads of membrane phospholipids oriented in their environment? a. The hydrophobic heads are oriented towards each other and the hydrophillic tails are oriented towards the extracellular fluid and the intracellular fluid.
You hopefully remember that phospholipids are the molecules that make up the plasma membrane. and all of the membranes of a human cell (nuclear membrane, lysosomal membrane, both mitochondrial membranes, endoplasmic reticulum, Golgi apparatus). They have a polar, hydrophilic head and two non-polar, hydrophobic tails.ou hopefully remember that phospholipids are the molecules that make up the plasma membrane. and all of the membranes of a human cell (nuclear membrane, lysosomal membrane, both mitochondrial membranes, endoplasmic reticulum, Golgi apparatus).
