Does the phagocytosis process involves specific membrane receptors?
no that would be facilitated diffusion. nice try though.
What are membrane receptors that attach phosphates to specific animo acids in proteins?
called receptor tyrosine-kinases
How does gene expression initiate?
Proteins (in short supply) interact with specific receptors on the cells outer membrane, triggering a cascade of events, which leads to the expression of specific genes and the production of the protein.
What hormones can cross the cell membrane?
steroid hormonesSteroidalHormones are steroids and go across the membrane through specific receptors - this is why a hormone will act on certain tissue only e.g. estrogen only on mammary glands, uterus etc.
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?

What part of the cell is stimulated by outside chemicals triggering the cell to carry out specific functions?
cell membrane receptors
Why are viruses so specific in the cell the infect?
Viruses have specific proteins on them which only binds to certain receptors, which are present in certain cell's plasma membrane.
The effect of a neurotransmitter on the postsynaptic cell occurs when the neurotransmitter?
binds to specific receptors on postsynaptic cell membrane

The cell types that are most responsible for presenting foreign antigens together with surface antigens to specific receptors on the membrane of T lymphocytes are the macrophages and?
dendritic cells
What are two classifications of sensory receptors?
There are many different sensory receptors, but olfactory receptors in the nose, and cones and rods in the eyes are two specific types of sensory receptors. Olfactory detects the chemical presence and your brain identifies it as a smell. The rods and cones of the eye process light and color to form images that your brain processes as vision.
When a cell or organ has the specific protein receptors either on the plasma membrane of cells or in the interior of cells to which specific hormone attach and therefore cause change those cells as?
lungs ,heart ,brain and iver

What water-soluble hormone would most likely bind to what membrane proteins?
Channel linked receptors bind to neurotransmitters. (also called ion channels and ligand gated ion channels) A ligand is the signal molecule i.e the neurotransmitter. Hormones bind to intracellular receptors because hormones are non polar and can cross the cell's plasma membrane. (also called cytoplasmic receptors)
What process involves the use of specific carrier molecules?
two processes requiring the use of protein carrier molecules?
