assist with movement and gathering food. The process by which T. thermophila obtains most of its nutrients is called phagocytosis. During phagocytosis, particles are consumed by a portion of the plasma membrane. This results in the formation of a vesicle, or phagosome, which then fuses with a lysosome in the cytoplasm to break down and digest food particles. However, a large fraction of bacteria engulfed by protozoa are not digested. Instead, they remain metabolically active and survive to be…

Organelles of Animal Cells The Nucleus: ~A large, round organelle visible under the microscope. Functions- Regulation • Controls the cell’s activities • Controls cell reproduction Contains genetic material - DNA that makes up the genes and chromosome. The Ribosome: ~Made of dozens of different proteins as well as RNA, also found in large numbers in the cytoplasm of living cells. Ribosome are typically composed of two subunits: • Large subunit • Small subunit “ Free” Ribosome makes…

Concerning nanotechnological consumer products, the most rapidly growing is the use of nanoparticles (NPs).(47) So far the knowledge regarding the safety aspects of NPs is still in its initial phase and greater efforts is needed to understand the interaction of NPs with the human body. (48) Several studies have reported that NPs always showed more serious toxicity than bulks and suggested that their size and the dose were the key factors influencing NPs toxic effects.(49) Despite of this, large…

endocytosis and types of each. Both exocytosis and endocytosis use vesicles to transport substances, and they both require energy. Endocytosis is a form of transport that allows a cell to engulf fluids and large molecules and bring them into the cell, and it has two main forms: pinocytosis and phagocytosis. Pinocytosis brings in fluids, while phagocytosis brings in solid particles. Exocytosis is a form of transport in which vesicles containing cell secretions fuse with the cell membrane. 10.…

The pathophysiology of methamphetamine abuse and addiction Introduction Addiction is a neurological disorder that impairs reward system in the brain (Peter and Charles, 2007). Methamphetamine is the second most illicitly abused drug after Cannabis in Australia (McKetin et al., 2009). It is one of the most powerful and addictive stimulant that causes brain dysfunctions. Methamphetamine increases release of neurotransmitter dopamine that is involved in reward and generation of pleasurable emotions…

of the Herpes Simplex Virus ( HSV) , Herpes Simplex Virus type 1( HSV-1) and Herpes Simplex Virus type 2 ( HSV-2) . HSV-1 produces painful blisters or cold sores on the lips. HSV-2 is responsible for Genital Herpes, which generates painful vesicles or ulcers in the genital area. Historically, it was thought that HSV-1 was specific for producing the oral lesions, and was not sexually transmitted. It has recently come to light that HSV -1 is increasingly isolated from genital lesions. In…

Cell respiration is affected when the heart stops. Cells are using up ATP. Therefore, carbon dioxide is building up in the cells and the PH levels cannot balance themselves. Glucose is needed to start glycolysis. Glycolysis is a series of chemical reactions that produces ATP from the glucose. Oxygen is needed for the mitochondria. The mitochondria are referred to as the powerhouse of cells. Carbon dioxide is not being released. The cells begin to die and the transport pump then stops working.…

at all. Some people have symptoms within a few days of contracting herpes, others weeks, and some even years. This sometimes presents a problem when trying to find out the point of contraction. The classic symptoms of genital herpes are sores, vesicles, or ulcers on the skin – sometimes call herpes lesions. They can look like a pimple/blister that can scab; they can often take 2-4 weeks to disappear. Many people discount these “lesions” for an insect bite, abrasion, ingrown hair, hemorrhoids…

the DNA of the cell. It is also used for cellular reproduction and it is often referred to as the brain of the cell as it controls what goes on. Golgi apparatus A group of fluid-filled flattened membrane bound sacs located close to the nucleus. Vesicles are regularly seen at the sacs' edges. It is stack of layer bound, flattened sacs, which gets protein from the ER and adjusts them. Golgi apparatus…

According to the cell theory, the cell is the smallest form of life but there are many parts of a cell which allow the cell to do the job it is assigned correctly. An example of a cell would be the animal cell, which is a eukaryotic cell or a cell that contains a plasma membrane. Inside the membrane there are parts of the cell called the organelles. (Animal Cell Structure, 2005) Organelles inside the cell have specific jobs to perform for the cell, organelles include the ribosomes, vacuoles,…
