Cell plasma in the human body

Definition Cell plasma or cytoplasm is the complete content of the cell with the exception of cell organelles. Cytoplasm is an organic fluid that forms the basic substance of every cell. Besides water, cytoplasm consists mainly of proteins, nutrients and enzymes that are essential for the cell’s function. Function of the cell plasma The cytoplasm … Cell plasma in the human body

What is the cell membrane? | Cell plasma in the human body

What is the cell membrane? In prokaryotic and eukaryotic cells, the cell membrane describes the envelope of the cell plasma. Thus, the cell membrane protects the cell from external influences. The basic structure of the cell membrane is the same for all cells. The basic structure is a double fat layer (lipid bilayer). This consists … What is the cell membrane? | Cell plasma in the human body

Cell membrane

Definition Cells are the smallest, coherent units from which organs and tissues are built. Each cell is surrounded by a cell membrane, a barrier consisting of a special double layer of fat particles, the so-called lipid double layer. Lipid bilayers can be imagined as two fat films lying on top of each other, which cannot … Cell membrane

What are the components of the cell membrane? | Cell membrane

What are the components of the cell membrane? Basically, the cell membrane is composed of a phospholipid bilayer. Phospholipids are building blocks consisting of a water-loving, i.e. hydrophilic, head and a tail formed by 2 fatty acids. The part consisting of fatty acids is hydrophobic, which means that it repels water. In the bilayer of … What are the components of the cell membrane? | Cell membrane

Functions of the cell membrane | Cell membrane

Functions of the cell membrane As the complex structure of cell membranes already suggests, they have many different functions to fulfil, which can vary greatly depending on the type and localisation of the cell. On the one hand, membranes generally represent a barrier. A function that should not be underestimated. In our body, countless reactions … Functions of the cell membrane | Cell membrane

Differences to the cell membrane of bacteria – Penicillin | Cell membrane

Differences to the cell membrane of bacteria – Penicillin The cell membrane of bacteria is hardly different from that of the human body. The big difference between the cells is the additional cell wall of the bacteria. The cell wall attaches itself outside the cell membrane and in this way stabilizes and protects the bacterium, … Differences to the cell membrane of bacteria – Penicillin | Cell membrane

What are Chromosomes?

Chromosomes are made of coiled DNA (deoxyribonucleinacid) and are found in the nucleus of every human cell. Although the number of chromosomes varies in each species, the amount of chromosomes in a species per body cell is identical. Humans have 23 pairs of chromosomes (diploid) or 46 individual chromosomes (haploid). However, comparison with other organisms … What are Chromosomes?

Ion Channel: Function & Diseases

An ion channel is a tansmembrane protein that forms a pore in the membrane and allows ions to pass through it. Ions are electrically charged particles; they can be postitive but also negatively charged. They are in constant exchange between the cell and its environment or another neighboring cell. What is an ion channel? The … Ion Channel: Function & Diseases

Chromosomal aberration – What is meant by this?

Introduction – What is a chromosomal aberration? A chromosomal aberration describes a deviation from the normal human chromosome configuration. A normal human chromosome set has 23 chromosome pairs of the same kind, which contain the entire genetic material. A chromosomal aberration can be both a numerical and a structural deviation of the chromosome set. Chromosomal … Chromosomal aberration – What is meant by this?

Causes of chromosomal aberration | Chromosomal aberration – What is meant by this?

Causes of chromosomal aberration There are different causes for the numerical and structural chromosomal aberrations. The numerical chromosomal aberration has a different number of chromosomes, but the chromosomes themselves look normal. In aneuploidy, single chromosomes are duplicated or missing, as in trisomy 21, for example, the most common cause is non-disjunction of chromosomes during meiosis. … Causes of chromosomal aberration | Chromosomal aberration – What is meant by this?
