The phosphate molecule - (PO4)3- - is an anion (negative ion).
The phosphate groups in the DNA molecule give it a negative charge.
Like signs give a positive answer. Unlike signs give a negative answer.
FFructose. Fructokinase phosphorylates the fructose molecule to give fructose-1-phosphate as product. 1 molecule of ATP is used and 1 molecule of ADP is released.
Multiplying a positive and negative number will give a negative result. The result is a negative number.
Fatty acids and glycerol may combine to form monoglycerides, diglycerides and triglycerides (normal fats and oils). Addition of a phosphate group to a diglyceride will give a membrane lipid (phospholipid).
In the human body, ADENOSINE TRIPHOSPHATE (ATP) is the major molecule that releases energy. This comprises the large ADENOSINE molecule and three negatively charged PHOSPHATE molecules. During cellular chemical reaction inside the cells' mitrochondria, one of the PHOSPHATE molecule is separated from the ATP producing two separate molecules: ADENOSINE DIPHOSPHATE (ADP) and one PHOSPHATE molecule. With this reaction, abundant energy is released.
++ = + +- = - Like signs always give me plus. Unlike signs always give me minus when I multiply! My maths teacher made us learn that! :D
Adenosine triphosphate (ATP) is composed of an adenine molecule bonded to a ribose sugar molecule, which in turn is connected to a chain of three phosphate groups. The phosphate groups are linked together by high-energy bonds that release energy when broken during cellular processes.
-- Ignore the signs. -- Find the difference between the two numbers. -- Give it the sign of the larger original number.
Energy forms because of breakage of high-energy bond between adenosine-diphosohate and a third phosphate bound to it. energy value is not significantly known but is said to have value around 7.3kCal(~30.5kJ). Energy formed is mostly chemical rather than physical.
vertical signs generally give instructions or tell you the law. horizontal signs give directions or information
In addition different signs you subtract and give the sign of the bigger number. Ex: 6+(-8)= -14
