MITOCHONDRIA Membrane-bound organelles responsible for important energyconversion reactions in eukaryotes. ENDOPLASMIC RETICULUM A membraneenclosed series of passages in eukaryotic cells in which proteins and lipids are synthesized. or “kernel”). It is surrounded by the nuclear Antibiotics kill bacteria but leave humans un-…
Mitochondria have a "bag within a bag" structure. This is necessary to: create two distinct regions with a concentration gradient between them, a form of potential energy.…
The perfect Psammosere consists of an Embryo Dune, the smallest dune at pH 8 and consisting of a little vegetation. Next is the Fore Dune slightly bigger consisting of more vegetation. Then there is the Yellow Dune and the Grey Dune, which are less sheltered and have lots of grasses on about 80% coverage. There is then a drop in height to the Dune Slack which often has water lying in a puddle as it goes below sea level. Because of the puddle of water it attracts water loving plants. Finally there is the Mature Dune consisting of trees; often birch and oak. The Mature Dune is the final dune of the Psammosere.…
The mitochondria is the site of ATP production for the cell. ATP is the energy currency of the cell. Mitochondria are nicknamed, the "powerhouse".…
f) There are no mitochondria in bacterial cells because they are single-cellular organisms, so they are very small and do not need energy.…
Mitochondria- The mitochondria is the energy supplier to the cell. It is enclosed by a double membrane, and is identifiable due to its cristae which tend to divide their interiors. This is like a power plant because the power plant supplies electricity to the entire town. Power plants are enclosed by the building walls and a fence for protection, such as a double membrane. It is also divided into many floors, such as the interior of the Mitochondria.…
Mitochondrion - this feature produces a substance called adenosine triphosphate (ATP) which is the carrier of energy in all cells.…
DQ 3: What organelle of the cell do you think is most important for life?…
A chromosome is necessary so that there is a “map” of the cells function and structure, cytoplasm is necessary as it is where most of the cell’s activity occurs, ribosomes are essential as they are the site of protein synthesis, which powers the activities of the cells, and the cell membrane is needed to give the cell structure and protection. Most cells have other structures based upon their function, and these extra structures are necessary in order for that cell to perform it’s function.…
A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins. The two membranes, however, have different properties. Because of this double-membraned organization, there are five distinct compartments within the mitochondrion. There is the outer mitochondrial membrane, the intermembrane space (the space between the outer and inner membranes), the inner mitochondrial membrane, the cristae space (formed by infoldings of the inner membrane), and the matrix (space within the inner membrane).…
Mitochondria: power plant of the cell, it makes energy, contains glucose and oxygen. (Both animal and plant cell)…
The depression while Herbert Hoover was president drove America into something they have never experienced before. For the first time, Americans experienced a lack or resources and money and they did not know how to help themselves. Hoover stated: “...Economic depression cannot be cured by legislative action or executive pronouncement…”[1] Hoover believed that the American people should be able to pull themselves out of a depression without the help of the government. People disagreed with Hoover’s ideas and wanted a new leader with ideas to help them out of the depression. Franklin Roosevelt created many programs during his presidency that helped aid the country struggling through the Great Depression. The New Deal (1933-1940), Roosevelt’s plan called for immediate relief, economic reform, and future recovery. The implementation of Roosevelt’s New Deal plan was successful in pulling the country out of the depression.…
Mitochondrion (pl. Mitochondria). This is a sausage-shaped organelle (8µm long), and is where aerobic respiration takes place in all eukaryotic cells. Mitochondria are surrounded by a double membrane: the outer membrane is simple, while the inner membrane is highly folded into cristae, which give it a large surface area. The space enclosed by the inner membrane is called the matrix, and contains small circular strands of DNA. The inner membrane is studded with stalked particles, which are the site of ATP synthesis.…
In W.W. Jacobs ¨The Monkey’s Paw, the first man who had the monkey’s paw was an old fakir who had put a spell on it to show that fate ruled people’s lives and if you chose to interfere with it then it would bring fate upon themselves. The old fakir had already used two out of the three wishes and wished for his third wish to be death. So the old fakir died and that’s how Sergeant Morris got the paw. Mr. White was hesitant about using the paw because he thought that the magical paw would not work.…
At one point, mitochondria were believed to have been their own organism around the time of prokaryotic life dominance on earth. The prokaryotes would 'eat' the mitochondria, settling them in the cells for a mutual…
