What else can I help you with?
Do plant and animal cells both have a mitochndria?
yes they both need energy to survive because they are eukaryotes
Does respiration occur in the mitochndria?
Two of three parts of aerobic respiration take place in mitochondria.Kreb cycle and electron transport chain.
How are bacterial cells different from animal cells?
A bacteria cell differs structurally from plant and animal cells because of its small size. A bacteria cell has flagella outside of the cell to help it move. A bacteria cell does not contain organelles. Only the chromosome and sometimes ribosomes are visible in a bacteria cell.
Four types of membranes and their locations?
The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes. Mucous membranes are tissues that line body cavities or canals such as the throat, nose, mouth, urethra, rectum, and vagina. Serous membranes line body cavities (peritoneum) and surround organs such as the lung (pleura) and heart (pericardium). The cutaneous membrane is the skin. This membrane is composed of a layer of epithelium over a layer of connective tissue. Synovial membrane is a layer of connective tissue that lines the cavities of joints, tendon sheaths, and bursae (fluid sacs) and makes synovial fluid, which has a lubricating function.
Why is the inner membrane of mitochndria folded so many times?
In cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed organelle found in most eukaryotic cells.[1] These organelles range from 0.5 to 10 micrometers (μm) in diameter. Mitochondria are sometimes described as "cellular power plants" because they generate most of the cell's supply of adenosine triphosphate (ATP), used as a source of the chemical energy.[2] In addition to supplying cellular energy, mitochondria are involved in a range of other processes, such as signaling, cellular differentiation, cell death, as well as the control of the cell cycle and cell growth.[3] Mitochondria have been implicated inseveral human diseases, including mitochondrial disorders[4] and cardiac dysfunction,[5] and may play a role in the aging process. The word mitocho ndrion comes from the Greek μίτος or mitos, thread + χονδρίον or chondrion, granule . Several characteristics make mitochondria unique. The number of mitochondria in a cell varies widely by organismand tissue type. Many cells have only a single mitochondrion, whereas others can contain several thousand mitochondria.[6][7] The organelle is composed of compartments that carry out specialized functions. These compartments or regions include the outer membrane, the , the inner membrane, and thecristae and matrix. Mitochondrial proteins vary depending on the tissue and the species. In humans, 615 distinct types of proteins have been identified fromcardiac mitochondria;[8] whereas in Murinae(rats), 940 proteins encoded by distinct genes have been reported.[9] The mitochondrial proteome is thought to be dynamically regulated.[10] Although most of a cell's DNA is contained in the cell nucleus, the mitochondrion has its own independent genome. Further, its DNA shows substantial similarity to bacterial genomes.
