Some of the examples of specialized cells are Reproductive cells, Nerve cells,blood cells. Red blood cells specialize in carrying oxygen throughout the body.

<u>Explanation:</u>

When a cell performs a function or a task that others cannot do then those cells are called as specialized cells. They are useful in performing special functions like transportation of something throughout the human body.Some of the cells are responsible in performing some special tasks that others cannot do.

Examples of specials ed cells includes nerve cells, blood cells, reproductive cells. These cells are responsible in performing a particular function. For instance nerve cells which are termed as neurons. They are responsible in sending signals with an electrical impulse. Blood cells are responsible in taking oxygen throughout the human body.

Hint: The wall which is present at the outermost of the cell wall acts as a glue between the different cells. . The secondary wall is not present in every cell, it is present in few cells that alter the growth of the primary wall.

Complete answer:

A cell wall is an outer structural layer present in only some types of cells, just outside the cell membrane. It is usually tough, flexible, and sometimes rigid. The cell wall is mostly composed of two layers and sometimes three layers too. The layers of the Cell wall are as follows-

- The primary cell wall is generally a flexible thin, and an extensible layer formed while the cell is growing i.e not fully developed. It is usually made up of cellulose and it is often permeable too.

-The middle lamella, a layer rich in pectins. It is the outermost layer that forms the interface between adjacent plant cells and glues them together.

-The secondary cell wall, if present, is a thick layer formed inside the primary cell wall after the cell is mature. it's not found in all cell types.

Additional Information: The cell wall is majorly composed of the cellulose microfibrils that are linked via hemicellulosic tethers to form the cellulose-hemicellulose network, which is embedded in the pectin matrix. The most common hemicellulose present in the primary cell wall is xyloglucan.

The outer part of the primary cell wall of the plant epidermis is mostly covered with the cutin and wax, forming a permeability barrier known as the plant cuticle.

Secondary cell walls contain a wide range of additional compounds that helps to enhance and modify their mechanical properties and permeability. The major polymers that make up wood (largely secondary cell walls) include cellulose, 35-50% .xylan, 20-35%, a type of hemicellulose, and lignin, 10-25%.

xplain how the chemical breakdown of glucose results in the production of a hydrogen ion concentration gradient across the mitoc

yan [13]

A high-energy electron is transferred along an electron transport chain to the inner mitochondrial membrane. Hydrogen is pumped out of the matrix space by the energy released. Through ATP synthase, the gradient produced by this forces hydrogen back through the membrane. when participating in the crucial process of oxidative phosphorylation.

Only a tiny portion of the glucose's totally free energy is released when it is transformed into pyruvate by the glycolytic process.
The breakdown of glucose into pyruvate within a cell's cytoplasm is known as glycolysis. The final phase of cellular respiration, known as oxidative phosphorylation, generates ATP using an ATP synthase gradient and a hydrogen ion gradient. The majority of the ATP produced during cellular respiration is produced during this process. Pyruvate can diffuse into mitochondria under aerobic conditions, where it enters the citric acid cycle and has reducing equivalents in the forms of NADH and FADH2.
