Which structure is composed of lipids and proteins?
Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments.
Which cell structure is responsible for homeostasis?
the cell membrane
The structure most responsible for maintaining cell homeostasis is the cell membrane.
Which organelle aids in homeostasis?
The cell membrane helps the organism in its fight to maintain homeostasis. The cell membrane assists in the maintenance of homeostasis by: Maintaining a fluid phospholipid structure. Phospholipids are molecules that have a head region that carries an electric charge attached to a lipid tail portion.
Where are proteins and lipids required for cell membrane?
Answer: The proteins and lipids, essential for building the cell membrane, are synthesized by the rough endoplasmic reticulum (RER). The ribosomes attached to the RER help in this process.
Do proteins maintain cell structure?
The collection of proteins within a cell determines its health and function. Proteins are responsible for nearly every task of cellular life, including cell shape and inner organization, product manufacture and waste cleanup, and routine maintenance.
What is the structure of homeostasis?
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.
What is the cell structure where proteins are made?
Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. For example, rapidly growing cells usually have a large number of ribosomes (Figure 5).
Where the lipids and proteins are synthesized?
The endoplasmic reticulum
The endoplasmic reticulum is an organelle that is responsible for the synthesis of lipids and the modification of proteins.
Where are the essential proteins and lipids required for cell membrane manufactured Class 9?
Answer: c) Endoplasmic reticulum. Explanation: Some of the proteins and lipids required for membrane biogenesis are synthesized by endoplasmic reticulum.
