What else can I help you with?
What is the region between the cell membrane and the nucleus called?
cytoplasm is located between the cell membrane and the nucleus.
The molecules in the cell membrane that serve as receptors or binding sites for hormones or other chemical messengers are?
The molecules in the cell membrane that serve as receptors or binding sites for hormones or other chemical messengers are typically proteins. These proteins help transmit signals from the outside of the cell to the inside, triggering specific cellular responses. The binding of a hormone or chemical messenger to its receptor on the cell membrane initiates a signaling cascade that ultimately affects the cell's behavior or function.
What keeps the cytoplasm and the nucleus from surrounding environment?
The cytoplasm is contained by the cell membrane, which acts as a barrier to regulate the flow of molecules in and out of the cell. The nucleus is enclosed by the nuclear membrane, which also helps to protect and regulate the movement of molecules in and out of the nucleus. Together, these membranes help to maintain the distinct internal environment of the cell.
Membrane-bound packet in cytoplasm that contains liquid?
This structure is likely a vesicle, which is a small membrane-bound sac found in the cytoplasm of the cell. Vesicles can contain various substances, including liquid, and are involved in transporting and storing molecules within the cell.
What can you conclude about the permeability of potato cytoplasm with respect to sucrose and water molecules?
The permeability of potato cytoplasm to water molecules is high, allowing water to easily move in and out of the cell. However, the permeability to sucrose molecules is lower, as they require specific transport proteins to pass through the cell membrane. This difference in permeability affects how sucrose and water move across the cell membrane in potatoes.
What are activities are performed by membrane proteins in multicellular organisms?
Chemical messengers to send information move molecules in and out of cells
What chemical messengers can pass through the plasma membrane and effect receptors in the cytoplasm?
Primary messengers are hormones (extracellular molecules) that conduct the signalling events by not passing though the membrane but binding on the cell surface receptors. Secondary messengers are small molecules that may cross the membrane which actually conduct the downstream signalling events inside the cell (intracellular). cAMP, cGMP, calcium ions, inositol triphosphate are a few secondary messengers. cell proliferation, differentiation, migration, metabolism, cell death such as apoptosis events are all controlled by signalling pathways.
What surrounds the organelles in the plasma membrane?
The cytoplasm surrounds the organelles in the plasma membrane. The cytoplasm is a gel-like substance composed of water, enzymes, salts, and various organic molecules. It fills the space inside the cell and provides a medium for chemical reactions to occur.
What is the region between the cell membrane and the nucleus called?
cytoplasm is located between the cell membrane and the nucleus.
What is the substance that fills the cell from the plasma membrane to the nuclear membrane?
The semifluid substance that fills a cell is cytoplasm.
What are chemical messengers in the cell that control the amounts of enzyme produced?
The chemical messengers in the cell that control the amounts of enzyme produced are called signaling molecules or ligands. These molecules bind to specific receptors on the cell membrane or inside the cell, triggering a signaling cascade that ultimately regulates the expression and activity of enzymes. Examples of signaling molecules include hormones, neurotransmitters, and growth factors.
Only those who have the proper on the cell membrane are activated by the chemical messengers?
Target Cell

What substance fills the space between the plasma membrane and the nuclear membrane?
The substance that fills the space between the plasma membrane and the nuclear membrane is called cytoplasm. Cytoplasm contains various organelles, such as mitochondria and endoplasmic reticulum, and plays a crucial role in cellular functions like metabolism and transport of molecules within the cell.
What is the gelatin like mixture inside of the cell membrane?
The gelatin-like mixture inside the cell membrane is called cytoplasm. It consists of water, salts, proteins, and other molecules that support the cell's structure and function. Cytoplasm plays a critical role in numerous cellular processes, including metabolism and transportation of molecules within the cell.
What keeps the cytoplasm and the nucleus from surrounding environment?
The cytoplasm is contained by the cell membrane, which acts as a barrier to regulate the flow of molecules in and out of the cell. The nucleus is enclosed by the nuclear membrane, which also helps to protect and regulate the movement of molecules in and out of the nucleus.

What does cytoplasm have in it?
Cytoplasm is a jelly like fluid between the cell membrane and nuclear membrane.In cytoplasm chemical reactions take place ,these reaction are collectively known as metabolism.
