In prokaryotic cells, the number of ATP generated from one glucose molecule is ___(a)36(b)38(c)34(d)32. Ans: Hint: in the bacterial cell, since there are no mitochondria, the whole process of respiration occurs within the cytoplasm so no ATP is ...
The protoplasm enclosed by the plasma membrane of cell, excluding the nucleus in eukaryotic cells and cellular DNA in prokaryotic cells. cy′to·plas′mic(-plăz′mĭk)adj. cy′to·plas′mi·cal·lyadv. American Heritage® Dictionary of the English Language, Fifth Edition. Copyright © ...
Prokaryotic cells do not have a nucleus; rather, they have a membraneless nucleoid region (open part of the cell) that holds free-floating DNA, according to Washington University. The entire DNA in a cell can be found in individual pieces known as chromosomes. Eukaryotic cells have many ...
胞质和胞核中。3. Organelles: Specialized Work UnitsAll eukaryotic cells contain most of the various kinds organelles, and each organelle performs a speciali 14、zed function in the cell. Organelles described in this section include ribosomes, the endoplasmic reticulum, the Golgi complex, Vacuoles, ...
ribosomes that make proteins, and a circular DNA molecule called a nucleoid where the genetic information is held. The majority of prokaryotic cells also have a rigid cell wall that is used for protection. All prokaryotic organisms are unicellular, meaning the entire organism is only one cell. ...
The prokaryotic tubulin homolog protein FtsZ assembles into the Z-ring at mid-cell to provide contractile force during bacterial cell division. Here, by tracing the status of FtsZ in living E. coli cells, we unexpectedly revealed a cytosolic organelle-like structure containing the FtsZ protein tha...
similar to the formation of crystals—spontaneous generation under their unified cell theory. However, this tenet was refuted by Robert Remak and Rudolf Virchow. They proposed that ‘Omnis cellula e cellula’,which is the Latin forall cells arise from pre-existing cells only and in no other ...
9. Prokaryotic cells have microbodies. 10. Mitochondria are self-replication. 11. Pinocytosis describes the intake of fluid into a a cell by a vacuole. 12. Both prokaryotic and eukaryotic cells have a supporting cytoskeleton. 13. Carotenoids (类胡萝卜素) are colorless molecules. 14. Grana (...
Fungi. Most eukaryotic cells contain a nucleus. There are a few exceptions, such as human red blood cells. Anucleus is a membrane-bound organellethat contains the DNA of that organism. The nucleus holds its contents safe by storing the DNA and conserving the DNA's structure within the cell...
