Which is a mechanism for restricting the movement of proteins in the plasma membrane? Choose one or more:
alexgriva [62]

Answer:

The correct answers are option A. "tethering proteins to the cell cortex", B. "using barriers such as tight junctions", C. "tethering proteins to the extracellular matrix", D. "forming a covalent linkage with membrane lipids", E. "tethering proteins to the surface of another cell"

Explanation:

According to the fluid-mosaic model, the components of cell membranes are in constant movement forming a barrier to avoid unwanted exterior component internalization and to avoid the loss of precious internal components. This constant movement could cause that proteins move across the plasma membrane. But, this is avoided by several mechanisms including:

A. Tethering proteins to the cell cortex. The cell cortex is a rigid structure made of actin and actomyosin. Proteins found in the plasma membrane are tethered to this structure to restrict their movement.

B. Using barriers such as tight junctions. Tight junctions are barriers found in epithelia made of claudin and occludin proteins. These barriers are impenetrable, which avoid the movement of proteins in the cell membrane.

C. Tethering proteins to the extracellular matrix. The extracellular matrix is made of several proteins and macromolecules that provide a structural and biochemical support to cells that are nearby. Proteins could be tethered to this rigid structure as well.

D. Forming a covalent linkage with membrane lipids. The proteins in the cell membrane that form a covalent linkage with membrane lipids are known as lipid-anchored proteins, or lipid-linked proteins.

E. Tethering proteins to the surface of another cell. When cell-cell communication take place it is possible that proteins in the cell membrane got tethered to the surface of the other cell.

Importance of photosynthesis to humans
enyata [817]
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

In the economic world, matter and energy are transformed for the purpose of creating utility (an enjoyment of life as understood
Viefleur [7K]

Both in Biology and Economy utility refers to the ability to perform functions, which largely depend on the input of energy. In consequence, both perspectives can be reconciled from a profitable point of view.

From a biological point of view, energy and matter are fundamental inputs that flow within biological systems in order to perform metabolic functions (e.g., growth, differentiation, reproduction, etc).

During biological processes, energy is converted into matter, which in turn serves as food for the organisms at higher trophic levels.

Moreover, in Economy, matter and energy are also fundamental inputs required for economic growth and social development.

In Economy, the energy is converted into matter during the construction of buildings and the development of infrastructure (technical as well as social) in a similar way that occurs with living systems.

Both in Biology and Economy, efficiency reduces the input of matter and energy required for development and growth, which can be translated in Economy as the ability to deliver services (e.g., mobility, heating, lighting, cooling, etc).
