Kind of receptors:

Ion channel coupled receptors act very slowly

G-protein contains only two subunits: alpha and beta units

Receptors coupled with G-protein are known as "seven-transmembrane receptors"

Ion channel coupled receptors are found mostly in the nervous system

Ion channel coupled receptors transform of chemical signals into the electrical signal by opening the channels

Steps of fertilization:

Passage of the sperm through the corona radiata

Penetration of the zona pellucida

Sperm binding with ZP1 of ZP, that is a specific sperm receptor

Entering of sperm together with mitochondria into the oocyte

Completion of the second meiotic division of the oocyte

Zona reaction:

Is the acrosomal reaction

Prevents fertilization of eggs by more than one sperm

Stop the ability of spermatozoa to adhere to and penetrate the zona pellucida

During the window of implantation, the blastocyst can attach to the endometrial epithelium

Implantation can only occur when the endometrium is receptive

Effects of fertilization include:

Restoration of haploid number of chromosomes

Determination of the sex of new individuals

Restoration of the dipoid number of chromosomes

Disappearing of the zona pellucida

Initiation of the cleavage of the zygote

Mitochondria:

Protects the cell from the effects of hydrogen peroxide

Are surrounded by two membranes

Contains enzymes of the respiratory chain in the inner membrane

Are responsible for storage of energy ATP molecules

Smooth endoplasmic reticulum:

Is a membranous organelle

Has no ribosomes bound to its cisterns

Is involved in protein synthesis

Is involved in steroid hormone synthesis

Protects cell from effects of hydrogen peroxide

Intermediate filaments:

Are made of keratin in epithelial cells

Are components of blood clot

Are not present in neurons

Can be found in the ground substance of connective tissue

Are made of vinculin in connective tissue

What is true about lysozymes?

Metaphase:

Migration of chromosomes to the equator plane of the cell

Initiation of cleavage furrow

End of cell division

Nuclear elvelope and nucleolar formation

Immunochemestry:

Is a technique based on specific reactions between antibodies and antigens

Immunohistochemical reactions could be a one or two step reaction

It is the advanced and sophisticated staining method that specifically shows the detected marker in the tissue

HE staining is an example of IHC reaction

Two step IHC reaction need to use labeled primary antibodies

It could be one step or two step

Two step IHC is needed to use primary and secondary antibodies

PAS technique is an example of IHC reaction

The first stage of nondividing cells during erythropoiesis is:

Orthochromatophilic erythroblasts

Polychromatophilic erythroblasts

Proerythroblast

Reticulocyte

What is true about the G protein?
