What 2 molecules make up the cell membrane?
Phospholipids and proteins are the two main types of molecules that make up the cell membrane. Phospholipids form a lipid bilayer that serves as the basic structure of the membrane, while proteins are embedded within this lipid bilayer and help to carry out various functions such as transport, signaling, and support.
What 2 fat-based molecules make up part of the structure of the plasma membrane?
Phospholipids and cholesterol are two fat-based molecules that make up part of the structure of the plasma membrane. Phospholipids form a lipid bilayer, creating a barrier that separates the interior of the cell from the external environment, while cholesterol helps maintain the fluidity and stability of the membrane.
What two processes work together to synthesize proteins in the cell?
transcription and translation
What two organelles produce protein?
The two organelles that produce protein are the ribosomes and the rough endoplasmic reticulum. The ribosomes manufacture proteins for the cell through protein synthesis. The rough endoplasmic reticulum produces proteins here that are often secreted by the cell and carried by the vesicles to the Golgi apparatus.
What term describes the structure of a cell plasma membrane because of its oily nature and embedded proteins?
The term used to describe the plasma membrane because of it's oily nature and embedded proteins is the fluid-mosaic model.The plasma membrane that surrounds each cell has two layers of phospholipids (fat with phosphorous attached).Each phospholipid molecule has a head that is attracted to water (hydrophilic) and a tail that repels water (hydrophobic) . Both the layers of the plasma membrane have the hydrophilic ends pointing to the outside forming the outer layer of the plasma membrane and the hydrophobic tails pointing inside and forming the inner layer of the plasma membrane.Proteins and substances such as cholesterol become embedded in the bi-layer of the plasma membrane giving it a mosaic look.At body temperature the plasma membrane has a liquid consistency like the vegetable oil and proteins and other substances are able to move across the plasma membrane. Due to this reason the plasma membrane is described using the term fluid-mosaic model.
What are the two important processes carried out by proteins?
The two important processes carried out by proteins are growth, repair, digestion, respiration, and the transmissions of nerve impluses.
What are the two principal types of molecules in plasma membranes?
The two principal types of molecules in plasma membranes are phospholipids and proteins. Phospholipids form the basic structure of the membrane, while proteins are embedded within or attached to the phospholipid bilayer and serve various functions such as transport, signaling, and cell recognition.
What are the two main groups in a plasma membrane of organic molecules?
The two main groups in a plasma membrane of organic molecules are lipids and proteins. Lipids, such as phospholipids, form the structure of the membrane, while proteins are embedded within the lipid bilayer and perform various functions such as transport, signaling, and cell adhesion.
Two functions of the proteins found in the plasma membrain?
Proteins in the plasma membrane play crucial roles in cell signaling, facilitating cell-cell communication and transmitting extracellular signals into the cell. They also help transport molecules across the membrane, serving as channels, carriers, or pumps for essential substances like ions and nutrients.
Which type of cells are surrounded by a plasma membrane made of two layers of phosphilipids and integrated proteins?
All living eukaryotic cells are surrounded by a plasma membrane made of two layers of phospholipids and integrated proteins. Prokaryotic cells also show this structure, but have additional layers of peptidoglycan and occasionally lipoproteins.
Classification of plasma proteins?
There are a large number of plasma classifications. These include cold, hot and warm plasmas, plasma ionization, collisional plasmas, neutral plasmas, plasma densities, magnetic plasmas, complex plasmas, active and passive plasmas, ideal and non ideal plasmas and high energy density plasmas.
Describe two important processes carried out by proteins?
Proteins play a crucial role in enzyme catalysis, facilitating biochemical reactions by lowering activation energy. Additionally, proteins are essential in cell signaling, allowing cells to communicate with each other and respond to external stimuli.
Name two proteins?
eggs and beef
What are the three forms in which carbon dioxide is carried by blood?
Carbon dioxide is carried by blood in three forms: dissolved in plasma, as bicarbonate ions, and bound to hemoglobin. This allows for efficient transport of carbon dioxide from tissues to the lungs for elimination.
Name two gases found in plasma?
The carbon dioxide and oxygen are the two main gases in plasma. When blood travels to the lungs the concentration of these two gases changes.
What two factors determine blood viscosity?
Blood viscosity is determined by hematocrit (the percentage of red blood cells in the blood) and plasma proteins (such as albumin and fibrinogen), which contribute to the thickness and stickiness of the blood. High hematocrit levels or increased plasma proteins can lead to increased blood viscosity, which can impact blood flow and circulation.
What are names of plasma proteins?
Some examples of plasma proteins include albumin, globulins, fibrinogen, and immunoglobulins. These proteins play key roles in various functions such as transporting substances, maintaining osmotic pressure, and immune response.
