What are the end products of cellular respiration?

Cellular respiration is a method for cells to obtain the energy that is stored in food. It takes place in three stages: glycolysis, the citric acid cycle and electron transport. Some stages of the process require oxygen while some do not. Eukaryotic cells produce two fewer ATP molecules than prokaryotic cells during cellular respiration due to the passing of NADH molecules from glycolysis through the mitochondrial membrane.

What happens when the chlorophyll molecule absorbs light?

Chlorophyll is a complex molecule with a main group composed of a set of cyclic hydrocarbons surrounding a ring of nitrogen atoms. The nitrogen atoms themselves surround a single magnesium atom. The carbon rings around the nitrogen atoms alternate between single and double bonds, and electrons flow relatively freely from one part to another. In part due to this and in part due to the very low elecronegativity of magnesium, the molecule loses electrons very easily. The electron shed when chlorophyll absorbs light alters special molecules in leaves in a way that allows them to break apart carbon..

What releases histamines and heparin?

Upon release, heparin slows clotting and thins the blood, which allows more blood to reach the affected area. Histamines actively draw blood cells to the area. These compounds, which are both important for the body's inflammatory response, are stored in compact granules inside the basophils and mast cells until infection or injury causes the cell to release them.\nProduced in the bone marrow, basophils and mast cells are part of the innate immune system and make up approximately 0.5 percent of all white blood cells. They belong to the class of white blood cells called granulocytes. When b..

How do you convert DMS to a decimal?

As an example, for an angle 41 degrees, 51 minutes, 8 seconds, the conversion takes four steps:\n1.\tRetain the whole number, 41, for degrees\n2.\tDivide the 51 minutes by 60 to get 0.85\n3.\tDivide the 8 seconds by 3600 to get 0.00222\n4.\tAdd 41 to 0.85 and 0.0022 to get the full decimal result of 41.85222\nConverting from decimal to DMS requires a slightly different approach. For the decimal angle 41.8522, the steps would be as follows:\n1.\tRetain the whole number, 41, for degrees\n2.\tMultiply the decimal, 0.85222, by 60 to get 51.13657. The 51 is the number of minutes\n3.\tTake the rema..

What are organic and inorganic acids?

Common examples of organic acids include acetic acid, lactic acid and citric acid. Common inorganic acids include hydrochloric acid, nitric acid and boric acid. Although this is not always the case, inorganic acids are usually stronger than organic acids.\nIt is possible to determine whether an acid is organic or inorganic by looking at the conjugate base. The conjugate base is formed when the acid is dissolved in water. Acids in water will dissociate, which means that the hydrogen atom separates from the rest of the acid. These dissociated hydrogen ions are what causes the pH of the solution ..

What is systemic bias?

A systemic bias occurs when a human subject comes to a general conclusion regarding a person or problem based on evidence that is unfair or unequally deliberated in some way. For example, affirmative action is a national policy designed to combat the systemic bias of discrimination based on race or sex. Affirmative action corrects this systemic bias by requiring companies to maintain a certain number of individuals from particular groups. Individuals maintain their own systemic biases through their loyalties to certain ideologies or beliefs. Large organizations are often criticized for maintai..

What is the definition of rate of natural increase?

The rate of natural increase measures the difference between live births and deaths in a year, divided by the mid-year population and multiplied by a particular factor. It measures the difference between the crude birth rate, or number of live births per year per 1000 population, and the crude death rate, or number of deaths per year per 1000 population. It is commonly expressed as a percent. As of 2013, the rate of natural increase in the United States is 0.5 percent as per the Population Reference Bureau.

What is the scientific name of a paramecium?

Paramecia use their cilia to move through a fluid environment and to direct food towards their mouths. One differentiation between paramecia and other ciliophores is that paramecia typically have elongated bodies, described as cigar- or slipper-like in shape. Additionally, paramecia have furrowed membranes that create food packets, known as vacuoles. Members of this genus have both a large and small nuclei, known respectively as the macronucleus and the micronucleus. The macronucleus holds the cell materials responsible for everyday survival, while the micronucleus stores and transmits genetic..

How do sodium lights work?

Low-pressure sodium lamps are frequently used in Europe for the purposes of outdoor lighting. These lights emit a vibrant lemon-colored yellow hue upon reaching their greatest internal temperatures. These lamps are made of sodium metal, which helps give lamps shape in their solid form. Sodium metal forms the backbone of the arc tube, which serves as a chamber to transmit sodium vapors that arise when low levels of heat are produced. As the air warms, the sodium vapor transforms into neon gas, which is red in appearance. As the gas heats, its red color transitions to orange and eventually reach..

What is the longest day of the year?

On the summer solstice, there is maximum daylight and the night is very short. This is the peak of summer in the Northern Hemisphere. In the Arctic Circle, there are 24 hours of daylight, as the sun does not set.\nThis day marks the winter solstice for regions in the Southern Hemisphere. Australia and New Zealand experience winter with very short days and long nights. In the Antarctic Circle, there are 24 hours of darkness.
