What else can I help you with?
Do T cells express MHC II?
No, T cells do not express MHC II. MHC II molecules are primarily found on antigen-presenting cells, such as dendritic cells, macrophages, and B cells, and are involved in presenting antigens to T cells for immune responses. T cells, on the other hand, express MHC I molecules, which present antigens to other immune cells.
What materials are expelled from cells during exocytosis?
During exocytosis, cells expel cellular waste, proteins, neurotransmitters, hormones, and other molecules packaged in vesicles. These materials are released from the cell into the extracellular space or targeted to specific locations outside of the cell.
Which substances are secreted at the endings of nerve cells?
Neurotransmitters are the substances that are secreted at the endings of nerve cells to transmit signals to other nerve cells or target cells. These neurotransmitters can include molecules such as dopamine, serotonin, and acetylcholine.
How do cells respond to contact with other cells?
Cells can respond to contact with other cells through a process called cell-cell communication. This communication can involve direct contact between cell surface molecules or the release of signaling molecules that can bind to receptors on neighboring cells. These interactions can trigger a variety of responses, such as changes in gene expression, cell growth, differentiation, or cell death.
What are two other differences plant and animal cell besides cell walls?
Plant cells have a large central vacuole and chloroplasts, neither of which are found in animal cells.
What do cells use to take in molecules or other cells?
active transport by endocytosis
Golgi bodies are organelles that process and package macromolecules such as proteins and lipids for export out of the cell Given this information what types of cells possess a large?
Cells that are actively involved in secretion, such as glandular cells or cells of the pancreas, often possess a large number of Golgi bodies. These cells produce and secrete large amounts of proteins and other molecules that require processing and packaging before they can be released from the cell.
Is cell larger than molecule?
Cells are larger than molecules. Cells normally have molecules inside them and constantly passing through their membranes. Cells normally contain water molecules along with glucose and other molecules.
Do T cells express MHC II?
No, T cells do not express MHC II. MHC II molecules are primarily found on antigen-presenting cells, such as dendritic cells, macrophages, and B cells, and are involved in presenting antigens to T cells for immune responses. T cells, on the other hand, express MHC I molecules, which present antigens to other immune cells.
What transfers energy from glucose to other molecules during redox reaction in cells?
Electrons transfer energy from glucose to other molecules during redox reactions in cells.
What transfers energy from glucose to other molecules during redox reaction cells in?
Electrons transfer energy from glucose to other molecules during redox reactions in cells.
What materials are expelled from cells during exocytosis?
During exocytosis, cells expel cellular waste, proteins, neurotransmitters, hormones, and other molecules packaged in vesicles. These materials are released from the cell into the extracellular space or targeted to specific locations outside of the cell.
Do cells combine to make atoms?
No, cells do not combine to make atoms. Atoms are the building blocks of all matter, including cells. Cells are made up of a combination of different atoms, such as carbon, hydrogen, oxygen, and nitrogen, organized into molecules that form the structure and function of the cell.
How many ATP molecules are in Cellular respiration?
Liver and cardiac cells produce 38.Other cells produce 36.
Why did the large cells not destroy the small aerobic cells they engulfed?
The large cells did not destroy the small aerobic cells they engulfed because of a mutualistic relationship where both cells benefit from each other. The small aerobic cells provide energy in the form of ATP through aerobic respiration, benefiting the large cells by increasing their efficiency. In return, the large cells offer protection and a stable environment for the small aerobic cells to thrive.
Does animal take on cells of eaten animal?
No. The digestive process breaks down the foreign cells. Their constituent molecules may be reused as is, or may be used as building blocks for other molecules, but the cells themselves are certainly not used directly.
Why is it harmful for cells to become too large?
Cells need to be small in order to efficiently transport nutrients and waste products across their membrane. If a cell becomes too large, it may have difficulty in transporting these essential molecules, leading to impaired function and eventually cell death. Smaller cells also have a higher surface area to volume ratio, which is important for exchanging materials with the environment.
