What type of macro-molecule make up transporters carriers and enzymes in the plasma membrane?
Transporters, carriers, and enzymes in the plasma membrane are primarily made up of proteins. These proteins can span the membrane, facilitating the movement of substances in and out of the cell, or they can act as enzymes that catalyze biochemical reactions. The specific structure and function of these proteins are determined by their amino acid sequences, which are encoded by the cell's DNA. Additionally, these proteins may interact with lipids and carbohydrates, contributing to their overall functionality in the membrane.
What is found in plasma but not usually in the tubular fluid?
Proteins are found in plasma but are generally not present in the tubular fluid of the kidneys due to their large size. However, small proteins may be filtered into the tubules under certain conditions.
What are names of plasma proteins?

What do proteins in the mitochondria do?
They have several function. They may be structural,protective etc.
What proteins carry plasma?
Plasma is a pale yellowish component of blood that has blood cells and suspension. It contains dissolved proteins such as serum albumin, globulin, clotting factors, hormones, as well as gases O2 and CO2 salts etc. No proteins are carrying plasma, but the reverse is true.

What items are NOT dissolved in plasma?
Items that are not dissolved in plasma include larger blood cells such as red blood cells, white blood cells, and platelets. Additionally, certain large proteins, such as some clotting factors, may exist in the plasma but are not dissolved in a free form. Instead, they remain suspended in the plasma. Other substances, like lipids or fat globules, typically require transport proteins to move through plasma.
What are the functions of proteins in cells?
the function of proteins in cell may be varied.structurally they repair the wear and tear and thus are building blocks.In cell as in plasma membrane they act as channels for transportation of materials across the membrane and thus are intrinsic and extrinsic ,proteins may act as receptors also in form of enzymes and thus contribute to metabolism we can take an example of G-proteins in signal transduction, etc.
What is the function of the ridosome?
These small structures function as factories to produce proteins. Ribosomes may be attached to the endoplasmic reticulum, or they may float in the cytoplasm.
Why don't proteins function properly unless they are immersed in water?
Proteins are dependent on water to maintain their three-dimensional structure, which is crucial for their proper function. Water molecules surround proteins and help to stabilize their structure by forming hydrogen bonds with the protein molecules. Without water, proteins may denature and lose their shape, leading to loss of function.
What will happen to the cell if the plasma membrane does not function well?
If the plasma membrane does not function well, the cell may not be able to regulate the passage of substances in and out properly. This can lead to a loss of cell integrity, destabilization of the internal environment, and ultimately cell death.

Functional and non functional plasma enzymes?
Functional plasma enzymes include those involved in blood clotting (e.g. thrombin), lipid metabolism (e.g. lipoprotein lipase), and immune function (e.g. complement proteins). Non-functional plasma enzymes may be present due to tissue damage, such as elevated levels of creatine kinase after a heart attack, or can be indicative of disease, such as increased levels of liver enzymes in hepatic disorders.
How might the plasma membrane of a plant cell change in response to the cold temperatures of winter?
In cold temperatures, plant cells may increase the amount of unsaturated fatty acids in the plasma membrane to maintain fluidity. This helps prevent the membrane from becoming too rigid and losing function. Plants may also produce antifreeze proteins to prevent ice crystal formation within the cells.
