What else can I help you with?
Do most animal cell membranes have proteins that pump sodium ions out of the cell and potassium ions into the cell?
Yes, most animal cell membranes have protein pumps known as sodium-potassium pumps that actively transport sodium ions out of the cell and potassium ions into the cell. This helps maintain the cell's electrochemical gradient essential for various cellular functions.
Most specialized cells remain in what phase of the cell's life cycle?
Specialized cells remain in the G0 phase of the cell cycle, where they are no longer actively dividing but are carrying out their specific functions within the organism.
What part of the plants absorbs light energy from the sun?
Chloroplast
Why does penicillin kill only actively multipling cells and lysozyme will kill cells in any stage of growth?
Penicillin inhibits transpeptidase, and enzyme that is necessary for bacterial cell wall synthesis. If a cell is not actively multiplying, then no cell wall synthesis is occurring and, therefore, penicillin does not inhibit the bacteria.
What is actively transported across plasma membranes?
Ions, glucose, amino acids, and certain proteins are actively transported across plasma membranes. This process requires the use of energy in the form of ATP to move substances against their concentration gradient.
What is a type of cell that does divide actively?
A meristematic cell
which cell is most actively photosynthesizing?
In plants, light passes through to the palisade mesophyll cells where most of the photosynthesis takes place.
How can you tell if a plant is photosynthesising?
you look at it stupid
How oxygen is passed from a red blood cell to an actively respiring muscle?
The oxygen passes through a bloodvessel called artery to an actively respiring muscle cell.
Are zebras producers?
No. Have you ever seen a zebra photosynthesising?
What actively regulates what enters and exits the cell?
the bladder
Which molecule would most likely be actively transported?
A larger molecule or a polar molecule that cannot passively diffuse through the cell membrane would most likely be actively transported. Examples include glucose, ions (such as sodium and potassium), and amino acids.
Do most animal cell membranes have proteins that pump sodium ions out of the cell and potassium ions into the cell?
Yes, most animal cell membranes have protein pumps known as sodium-potassium pumps that actively transport sodium ions out of the cell and potassium ions into the cell. This helps maintain the cell's electrochemical gradient essential for various cellular functions.
How do drugs used to treat cancer affect cell growth?
Most drugs used to treat cancer kill actively growing/replicating cells.
What is a primary bone marrow cell type that remains actively mitotic?
The primary bone marrow cell type that remains actively mitotic is known as the hemocytoblast.Osteocytes
What moves within the Cell?
The actively accurate term "cytoplasmic streaming" shows what moves within the Cell.
Cell types are most sensitive to radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
