What else can I help you with?
What cell controls all the movement in the cell?
The nucleus, specifically through its regulation of gene expression, controls the production of proteins that are involved in cell movement. Additionally, the cytoskeleton plays a key role in cell movement by providing structural support and facilitating movement of organelles.
What regulation of blood sugar is accomplished by what organ?
pancreas
What two organelles function in the regulation of water within a cell?
The two organelles that function in the regulation of water within a cell are the cell membrane and the vacuole. The cell membrane controls the movement of water into and out of the cell, while the vacuole helps maintain water balance by storing and releasing water as needed.
The plasma membrane separates the?
The plasma membrane separates the inside of a cell from its external environment. It is a selectively permeable barrier that controls the movement of substances in and out of the cell, allowing for the regulation of cellular processes and maintaining cell homeostasis.
What is pinocytosis and phagocytosis accomplished by in a cell?
Pinocytosis is the process by which a cell engulfs liquids or small particles by forming vesicles. Phagocytosis, on the other hand, is the process by which a cell engulfs solid particles by forming pseudopods around the particle to form a vacuole. Both processes are accomplished by the cell's plasma membrane.
What brainstem produces its own type of cell?
The midbrain, in particular the substantia nigra, produces a specific type of cell called dopaminergic neurons. These neurons play a crucial role in the regulation of movement and are primarily affected in Parkinson's disease.
What type of cell doesn't respond to a cell's growth regulation signals?
Cancer?
Is growth accomplished by both cell division and cell enlargement?
Yes, both cell division and cell enlargement result in growth.
Movement of sodium ions from a region of lower concentration inside a cell toward a region of higher concentration outside the cell is accomplished by?
the sodium-potassium pump, an active transport protein that uses energy from ATP to move sodium ions out of the cell against their concentration gradient.
What part of the cell allows for substance to go in and out of it?
The cell membrane controls the movement of substances in and out of the cell. It is selectively permeable, allowing certain molecules to pass through while blocking others. This regulation helps maintain internal conditions necessary for the cell to function properly.
What is the movement of the stomach?
The movement of the walls of the stomach is accomplished by a group of smooth muscle that undergoes what is called peristaltic action.
What Controls the passage of substances into and out of a animal cell?
The cell membrane, made up of phospholipids and proteins, controls the passage of substances into and out of animal cells. Selective permeability allows for the regulation of what molecules can enter and leave the cell, maintaining internal conditions necessary for proper cell function. Transport proteins, such as channels and carriers, play a key role in facilitating the movement of specific molecules across the cell membrane.
