What else can I help you with?
Movement of a substance across a cell membrane using chemical energy occurs during?
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.
What happens to the portion of the cell membrane that surrounds a large molecule during endocytosis?
The portion of the cell membrane that surrounds a large molecule during endocytosis forms a vesicle called an endosome. This endosome then fuses with other cellular structures, such as lysosomes, to break down and digest the large molecule for further processing.
Is the nuclear membrane present during interphase?
Yes, the nuclear membrane is present during interphase.
When does the nuclear membrane and nucleolus reappear?
The nuclear membrane reforms during late telophase of mitosis or meiosis, while the nucleolus reappears during interphase.
Where does osmosis occur in the digestive system?
Osmosis occurs in the small intestine during the process of nutrient absorption. Water moves through the semi-permeable membrane of the intestinal cells to maintain osmotic balance, allowing nutrients to be absorbed into the bloodstream.
What is the process by which the vesicle of a cell transports a substance to the cell surface and then fuses with the membrane to release substance from the cell is called what?
The process by which a vesicle transports a substance to the cell surface and then fuses with the membrane to release the substance from the cell is called exocytosis. During exocytosis, the vesicle membrane merges with the plasma membrane, allowing the contents of the vesicle to be expelled into the extracellular space. This process is essential for various cellular functions, including secretion of hormones, neurotransmitters, and other important molecules.
When does movement of a substance across a cell membrane using chemical energy occur?
During osmosis and uptake of minerals.
Cell membrane that forms a pouch around a substance?
The process you are referring to is called endocytosis. During endocytosis, the cell membrane invaginates to surround a substance, creating a vesicle or pouch. This allows the cell to take in nutrients or other substances from its surroundings.
How are vesicles typically formed?
chemical energy that is contained in and transported by the molecule called (ATP) Adenosin Tri Phosphate.
Movement of a substance across a cell membrane using chemical energy occurs during?
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.
When is acetyl produced?
During pyruvate processing
What happens to the portion of the cell membrane that surrounds a large molecule during endocytosis?
The portion of the cell membrane that surrounds a large molecule during endocytosis forms a vesicle called an endosome. This endosome then fuses with other cellular structures, such as lysosomes, to break down and digest the large molecule for further processing.
What are suicide sacs also known as?
Lysosome contain digestive enzymes for almost all type of organic material. If their covering membrane breaks as it happens during injury to cell, the digestive enzymes will spill over cell content and digest the same. As lysosomes are organelles which on bursting can kill cells possessing them ,they are called suicide bags
Why lysosomes are the suicidal bags of the cell?
Lysosomes are bags containing hydrolytic enzymes. These enzymes can break the living cell. Hence, lysosmes are called the Suicidal Bag of cells.
Which organelle can be called digestive bags of the cell?
Lysosome contain digestive enzymes for almost all type of organic material. If their covering membrane breaks as it happens during injury to cell, the digestive enzymes will spill over cell content and digest the same. As lysosomes are organelles which on bursting can kill cells possessing them ,they are called suicide bags.
In which organs food does not pass through during digestion?
During digestion, food does not pass through the liver, pancreas, or gallbladder. These organs play crucial roles in digestion by producing bile or digestive enzymes and processing nutrients, but food itself does not travel through them. Instead, they contribute to the digestive process by aiding in the breakdown and absorption of nutrients in the intestines.
Is the nuclear membrane present during interphase?
Yes, the nuclear membrane is present during interphase.
