When a phospate group is removed from an ATP molecule energy is?
When the outer phosphate group detaches from ATP, energy is stored.
How does ATP release its energy?
ATP works by losing the endmost phosphate group when instructed to do so by an enzyme. This reaction releases a lot of energy, which the organism can then use to build proteins, contact muscles, etc. The reaction product is adenosine diphosphate (ADP), and the phosphate group either ends up as orthophosphate (HPO4) or attached to another molecule (e.g. an alcohol). Even more energy can be extracted by removing a second phosphate group to produce adenosine monophosphate (AMP). When the organism is resting and energy is not immediately needed, the reverse reaction takes place and the phosphate group is reattached to the molecule using energy obtained from food or sunlight. Thus the ATP molecule acts as a chemical 'battery', storing energy when it is not needed, but able to release it instantly when the organism requires it.
What is the number of the group in which the element have a stable outer energy level?
group 18
What is the number of group in which the elements have a stable outer energy level?
group 18
Which family on periodic table has a filled outer energy level?
The noble gases family in Group 18 have a filled outer energy level, making them very stable and unreactive.
The group that needs one more electron to fill its outer energy level?
The group that needs one more electron to fill its outer energy level is the group of elements located on the right side of the periodic table known as Group 17, or the Halogens. These elements have seven valence electrons and are just one electron short of a full outer energy level.
How many outer electrons are in Sr?
There are two outer electrons in strontium (Sr) since it belongs to Group 2 of the periodic table. Group 2 elements have 2 electrons in their outer energy level.
In which group are the elements unreactive because their outer energy levels are full?
STUDY
How many electrons are in the outer energy level of xenon?
There are 8 electrons in the outer energy level of xenon. Xenon belongs to the noble gas group on the periodic table, which have a full outer energy level with 8 electrons.
What kind of outer energy shell do elements in family 18 have?
The outer energy shells in the group 18 elements, called the noble gases, have a complete octet of ns2np6, where n is the highest energy level. The only exception is helium, which has an outer energy shell of 1s2.
What group of elements has a staple number of electrons in their outer energy level?
Group 18 elements have a stable octet.
Which group in the periodic table has a stable number of electrons in their outer energy levels?
noble gases or group 1
