Homologues are chromosome pairs of the same length, centromere position, and staining pattern with genes for the same characteristics at corresponding locations. One homologous chromosome is inherited from the organism's mother, the other from the organism's father during sexual reproduction. The crossing over, or synapse, occurs during meiosis, which is the process of gamete formation.

Using what you know about the

Soloha48 [4]

The term mosaic is used in arts for an art piece that is composed of many small pieces of materials like stones or glasses. However, in biology it is used for a structure that is made up of different types of cells.

Now if we have to describe a biological mosaic structure , then there is no perfect option than the structure of a cell membrane of animals' cells. Cell membrane is not made up of two types of cell at all but it is a structure that is composed of a lipid bilayer in which proteins are floating as you can see in picture.

The structure was explained as mosaic by fluid mosaic model. If we take a deep look, the double layer of lipids are made up of phospho lipids, which contain two fatty acid tails and a lipid head. The heads are hydrophilic and are outside while tails are hydrophobic and they are inside. This structure has alot of importance as per the function of cell membrane because it maintains the cell's internal environment and separates it from outer environment. This is because

As cell is surrounded by an environment which contain water in excessive amount, therefore nature has made cell membrane in a way that hydrophobic tails do not face water and stay inside the double membrance while hydrophillic heads face the water region outside the cell as well as inside the cell (cytoplasm that contains alot of water content too).

Hope it helps!

For each molecule of glucose that is processed by glycolysis and the citric acid cycle, what is the total number of nadh fadh2 m

elena-14-01-66 [18.8K]

12 is the total number of NADH FADH2 molecules that will be produced.

In each citric acid cycle, one molecule of FADH2 is formed during the conversion of succinic acid to fumaric.

The CAC is called a cycle because the starting molecule, oxaloacetate is regenerated at the end of the cycle.

It is also known as Krebs cycle. This is actually a part of a huge process called cellular respiration. The citric acid cycle captures the energy stored in the chemical bonds of acetyl CoA (processed glucose) in a step-by-step process, trapping it in the form of high-energy intermediate molecules.

NADH:- It is an energy shuttle that delivers high energy electrons to the electron transport chain where they eventually get to power the production of 2 to 3 ATP molecules.

FADH:- This is another energy shuttle that carries high energy electrons to the electron transport chain, where they will ultimately drive production of 1 to 2 ATP molecules.
