What are metabolically inactive cells?
Metabolically inactive 3T3 cells can substitute for marrow stromal cells to promote the proliferation and development of multipotent haemopoietic stem cells. J Cell Physiol.
What is a metabolically active cell?
Metabolically active means that there are a series of enzyme-catalysed reactions occurring in cells, known as metabolic pathways. Tumor cells are usually metabolically active (hungry) and will take up more sugar (glucose) than normal cells.
Which phase is metabolically inactive?
The interphase cell is metabolically inactive.

Is bacterial membrane is metabolically active?
Our new approach improves viability PCR by enabling it to also discriminate between cells with an intact cell membrane and the ability to actively maintain bacterial homeostasis and cells that have an intact membrane but are metabolically inactive.
What is the meaning of metabolically?
Metabolic: Relating to metabolism, the whole range of biochemical processes that occur within us (or any living organism). The term “metabolic” is often used to refer specifically to the breakdown of food and its transformation into energy.
Why are small cells more metabolically active?
higher surface area volume ratio. The higher nuclear cytoplasmic ratio allows the nucleus to have better control on metabolic activities. Whereas, the higher surface area volume ratio allows quicker exchange of materials between the cell and its surrounding.
Is inactive and resting stage?
Previously interphase is called resting stage because there is no apparent activity related to cell division. The interphase cell is metabolically quite active. As the synthesis of DNA and proteins occurs in interphase so, it is considered as metabolically active phase.
Which phase of cell cycle is metabolically active?
During G1, the cell is metabolically active and continuously grows but does not replicate its DNA. G1 is followed by S phase (synthesis), during which DNA replication takes place.
Which is the thickest wall layer?
(3) Secondary cell wall: Once the primary cell wall is completely grown, this wall grows inside the primary cell wall. This layer is also thickest in nature. Thus, the option (C) is correct.
Why are some bacteria metabolically active in Hot Springs?
A spring which is synthesized from the appearance of geothermally heated ground water from the earth’s crust is known as hot spring. Bacteria which live in hot springs are metabolically active because of the bacteria have high optimal temperatures.
What are the 3 main types of bacterial cell walls?
Types of cell wall
- Gram positive cell wall. Cell wall composition of gram positive bacteria. Peptidoglycan. Lipid. Teichoic acid.
- Gram negative cell wall. Cell wall composition of gram negative bacteria. Peptidoglycan. Outermembrane: Lipid. Protein. Lipopolysaccharide (LPS)
