the kidney and the heart. Often called the powerhouse of the cell‚ the mitochondria produce 90% of the energy that the body needs to function. The mitochondria’s main responsibility is to convert food and oxygen into life- sustaining energy in the form of adenosine triphosphate for cells to then use for specific functions. People with mitochondrial disease cannot make this conversion. Other than the nucleus‚ the mitochondria is the only part of the cell that has its own DNA. Mitochondrial DNA is

Mitochondria Mitochondria are responsible for energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP)‚ which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy‚ such as the flagellum. The role of the mitochondria is very important in respiration. In the presence

The process of photosynthesis requires an organelle called chloroplast and a pigment called chlorophyll The energy of the light is absorbed by chlorophyll and in turn supplies the plant with energy to transform carbon dioxide and water into oxygen and carbohydrates.

With a title such as Power‚ Sex‚ Suicide and a subtitle promising to give an answer to the question: ‘what is the meaning of life?’ this book about mitochondria‚ written by Nick Lane‚ certainly creates high expectations. At first glance a book regarding mitochondria might seem to be like a textbook‚ no matter how intriguing its title is. However‚ Lane circumvents this both by using a writing style that is distinct from anything you might find in a textbook and by touching upon some of the most intriguing

Drug Cards Ramipril: Functional class: Antihypertensive Chemical class: ACE inhibitors Action: ACE inhibitors reduce ACE. ACE converts angiostenin I to angiostenin II‚ which narrows heart vessels‚ which causes high BP. ACE inhibitors prevent ACE from converting angiostenin I to angiostenin II. This results in the dilation of blood vessel‚ which lowers BP. Adverse effects: Hypotension‚ angina‚ headache‚ fatigue‚ proteinuria‚ ‚ rash‚ sweating‚ cough. Contraindications: breastfeeding children

I. Describe the structure and function of the nucleus and mitochondria. The mitochondria is a semi-autonomous organelle which reproduces by bynary fission and has its own DNA. Its main function is to produce the energy intermediate ATP‚ through ATP synthase. Mitochondria could be considered a cell inside a cell. It has its own membranes (inner and outer membranes)‚ its ribosomes (to produce the proteins encoded in its DNA)‚ a matrix -- where aerobic respiration occurs. The invaginations of the inner

AN INVESTIGATION OF PHOTOSYNTHETIC ELECTRON TRANSPORT OF CHLOROPLASTS FROM _SILVERBEET LEAVES_ Introduction Photosynthesis is the process by which plants use the energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy is associated with the actions of the green pigment‚ chlorophyll. Light Dependent Reactions are the initial stage of photosynthesis‚ in which solar

Explain in detail why palisade cells in plants contain many chloroplasts Palisade cells are cells which are found within the leaves of many plants. They contain chloroplasts‚ which convert the energy in light to chemical energy through photosynthesis. The cylindrical shape of palisade cells allows a large amount of light to be absorbed by the chloroplasts. Beneath the palisade mesophyll are the spongy mesophyll cells‚ irregularly-shaped cells that having many intercellular spaces to allow the

Lil Dejay C4 2/10/14 Photosynthesis: Making Energy Chloroplasts Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis‚ and to store food energy. Chloroplasts contain the pigment‚ chlorophyll. Chlorophyll absorbs most of the colors in the color spectrum‚ and reflects only green and yellow
