Structural polysaccharides are those that are present in the cell walls of plants. Chitin and cellulose are two examples of polysaccharides.

'What are polysaccharides?'

These are referred to as complex biomolecules since a chain of monosaccharides makes them up. The linkages that are forming in this instance are glycosidic in nature. Here, simple sugars like glucose, fructose, and others frequently form monomers.

As is well knowledge, a polysaccharide is created using the same procedure as a monosaccharide and glycosidic linkages. A molecule of oxygen connects two rings of carbon to form the bond. A bond is created when a monosaccharide's hydroxyl group loses hydrogen and a molecule's carbon loses a hydroxyl group.

Ras is a small G protein that plays a central role in cell signal transduction. It is a signal transducer that binds to growth factor receptors, such as epidermal growth factor receptor (EGFR), and activates the MAP kinase signal transduction pathway.

When mutations of Ras occur, it can cause an overactivation of this signal transduction pathway, leading to uncontrolled cell growth and proliferation, which is associated with cancer. The uncontrolled cell growth and proliferation is due to the increased production of the proteins involved in the MAP kinase pathway, such as cyclin D1, c-Myc, and Bcl-2, which are involved in the cell cycle and promote cell survival.

The overactivation of the MAP kinase pathway also triggers the production of angiogenesis factors, which promotes tumor formation. Thus, mutations of Ras are associated with cancer because they lead to the overactivation of the MAP kinase signal transduction pathway, which promotes uncontrolled cell growth and proliferation and the formation of tumors. Hence, the correct answer is option (b) Ras binds to growth factor receptors.

Answer:

The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues.

The structure responsible for packaging proteins for export from the cell after protein synthesis is complete is the endoplasmic reticulum (ER).

The ER is a membrane-bound organelle that is involved in many cellular processes, including the folding, modification, and transport of proteins. The ER consists of two distinct sections: the rough ER, which is studded with ribosomes, and the smooth ER, which is not.

During protein synthesis, the proteins are transported from the ribosomes on the rough ER to the smooth ER. Here, they are modified and packaged into vesicles, which are then transported to other parts of the cell or to the cell surface. From here, they can be exported to other cells or to the extracellular environment.

In this way, the ER is essential for correctly packaging proteins for export from the cell after protein synthesis is complete.

The ability of diffusion and motor proteins to transfer nutrients and waste materials is maximized in small cells. The ability of a cell to send commands for cellular operations is influenced by cell size.

Diffusion increases as surface area increases. The size of cells is constrained by the necessity of allowing nutrients and gases to enter and exit the cell. It becomes more challenging for nutrients and gases to enter and leave a cell as it grows larger.

A cell's volume expands more quickly than its surface area as it grows. The surface volume ratio is the only element limiting the size of the majority of the cell. The nucleo-cytoplasmic limits the size of the cell.

The time period from the start of atrial contraction to the end of atrial repolarization is known as the atrial cycle.

This cycle begins with the atrial depolarization or contraction, which is triggered by an electrical impulse from the sinoatrial node. This contraction results in a wave of depolarization that travels across the atrial muscle, causing it to contract.

After the contraction, the atrial cells then repolarize, returning to their resting state. This repolarization is completed by the end of the atrial cycle, and the cycle then repeats itself.

The atrial cycle is important in regulating the heart rate, as it helps to coordinate the electrical impulses that trigger the heart's contraction and relaxation.

Adenosine triphosphate (ATP) is a cellular energy source that is used and stored.

The structure of ATP is a nucleoside triphosphate composed of a nitrogenous base (adenine), a ribose sugar, and three consecutive phosphate groups.

Mitochondria are small organelles within cells that are responsible for releasing energy from food. This process is called cellular respiration. For this reason, mitochondria are often referred to as the cell's powerhouses. By donating a phosphate group to another molecule, ATP can power cellular functions, a process known as phosphorylation.This transfer is carried out by specialized enzymes that couple energy release from ATP to energy-requiring cellular activities. This chemical energy is stored in the pyrophosphate bond between her two phosphate groups at the end of ATP. When a cell needs energy to function, ATP cleaves her third phosphate group, releasing the large amount of energy stored in the bond between the third and her second phosphate group. emit.

The major structural difference between plant starches and glycogen is in their branching pattern.

Starch, which is found in plants, is made up of two types of molecules: amylose and amylopectin. Amylose is a linear chain of glucose units, while amylopectin is a branched chain of glucose units. The branching of amylopectin allows for the efficient packing of glucose molecules in the starch granules, but the branching is relatively limited.

On the other hand, glycogen, which is found in animals, is a highly branched polymer of glucose units. Each glucose unit in glycogen is connected to many other glucose units via branches. This high degree of branching allows glycogen to store large amounts of glucose in a small space, making it an efficient storage form of glucose in animals.

In summary, Plant starches have limited branching while glycogen is highly branched, which makes glycogen more efficient in storing large amounts of glucose in small spaces.

A stage of the cell cycle lasts a variable period of time and is attributed to cells that are neither dividing nor preparing to divide is G0

The cell cycle or proliferation is a continuous and repeated cycle of DNA replication  in the chromosomes. which then separates the results of the duplication until there are two new identical cells. Successful proliferation requires a unidirectional and orderly transition from one phase of the cell cycle to the next.

The cell cycle is divided into two functional phases, namely the S and M phases and the preparatory phase G. The G phase consists of the G1 and G2 phases, namely the synthesis phase of the substances needed in the next phase. When a cell is in the G1 phase for too long, then the cell will be considered to be in the G0 phase. The G0 phase is the normal cell phase when there is no DNA synthesis and no mitosis. The GO phase occurs at one or more times when it is necessary for maintenance so that it is no longer actively proliferating.
