What acts like a nucleus in a cell?
The nucleus in a cell is an organelle that acts as the control center, housing the cell's genetic material (DNA). It directs cellular activities and plays a key role in regulating gene expression and cell division.
What is the key function of the nucleus?
The nucleus acts as the cell's control center.
What is the key function of the necleus?
The key function of the nucleus is to store the cell's genetic material, such as DNA, and regulate gene expression. It acts as the control center of the cell, coordinating cellular activities and ensuring proper cell division.
What is the key to controlling the chemical pathway of the cell?
The key to controlling the chemical pathway of the cell lies in regulating and coordinating the activity of enzymes, which are the key catalysts in these pathways. Enzymes can be activated or inhibited through various mechanisms, such as allosteric regulation, covalent modification, and gene expression control. By manipulating these regulatory mechanisms, the cell can finely tune and adjust its chemical pathways to meet its metabolic needs.
What part of the cell protects the cell from invaders?
The cell membrane acts as a barrier that protects the cell from invaders by controlling what enters and exits the cell. Additionally, the immune response triggered by the cell's internal defense mechanisms, like lysosomes and phagocytes, play a key role in protecting the cell from invaders.
Which cell organelle acts as the supporting skeletal framework of the cell?
The cytoskeleton is the cell organelle that acts as the supporting skeletal framework of the cell. It is made up of protein filaments that provide structure, support, and shape to the cell. The cytoskeleton also plays a key role in cell motility, intracellular transport, and cell division.
What is the key function for a cell membrane?
The key function of a cell membrane is to regulate the passage of molecules in and out of the cell. This selective permeability helps maintain the internal environment of the cell and allows it to communicate with its surroundings.
Can you copy a cell phone like a key?
i think no it will break
What a receptor protein in a membrane that recognizes a chemical signal is most similar to?
A receptor protein in a membrane that recognizes a chemical signal is most similar to a lock on a door, where the chemical signal acts as the key that fits into the lock to initiate a response. Just like a lock and key, the receptor protein and the chemical signal must fit together in a specific way for the response to occur.
What is the major component of a typical animal cell determines structure and function?
The cell membrane is a major component of an animal cell that determines its structure and function. It acts as a protective barrier, regulates the passage of substances in and out of the cell, and plays a key role in cell communication and signaling.
What jellylike is the site of all cellular chemical activities?
Cytoplasm is the jellylike substance inside cells where most cellular chemical activities take place. It surrounds the cell's organelles and is a key component in maintaining cell structure and function.
How does insulin bring sugar down to normal levels after a meal?
insulin acts as a key to turn on the active transport of sugar across cell membranes.
