Which cell structure is the source of energy for a cell quizlet?
How does the structure of ATP make it an ideal source of energy for the cell? ATP's structure makes it an ideal energy source because it is like a rechargeable battery that releases energy by breaking the bond of one of its phosphates and stores energy by forming bonds with new phosphates.
Which of the following is the energy of the cell?
Solution : ATP (adenosine triphosphate) is called energy currency of cells. ATP is energy rich compound where energy is present in terminal pyrophosphate bonds.
What is the most common source of energy for cells?
ATP is the main source of energy for most cellular processes. The building blocks of ATP are carbon, nitrogen, hydrogen, oxygen, and phosphorus.
Where do cell get their energy?
As we have just seen, cells require a constant supply of energy to generate and maintain the biological order that keeps them alive. This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells.
How does ATP provide energy to a cell?
Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell.
What directly provides energy needed for cell functions?
Answer and Explanation: The compound that directly provides energy for cellular work is adenosine triphosphate, (ATP) or choice E. Adenosine triphosphate is made up of the compound adenine and the sugar made up of five carbons called ribose.

Cells of prokaryotes differ from eukaryotes based on their structure. Eukaryotic cells are much more evolved than prokaryotes. They contain a well-defined nucleus and other important cell organelles to perform various metabolic activities.
Why are cell walls rigid?
Cell walls being rigid resist the expansion of the cell and establish turgidity due to endosmosis. Cell walls being rigid resist the expansion of the cell and establish turgidity due to endosmosis that maintains an erect posture of the young shoots.
What are the units of life?

Why are eukaryotic cells important?
Eukaryotic cells need a lot of chemical activities to support their complicated structure and function. To keep these activities separate from each other, these cells use membrane-bound little structures also called ‘organelles’ within themselves. These are important because they carry out some very crucial functions in cells.

Why do plants have guard cells?
Guard Cells: The lower surface of the leaf has little holes in it called stomata to allow gases to exchange. Each stoma is surrounded by two guard cells. Most plants close their stomata at night when they don't need carbon dioxide, as there is no light for photosynthesis, to prevent water loss. The guard cells have adaptations to open and close the stomata.

What are cells made of?
Cells Are Made From a Few Types of Atoms
What are the characteristics of a cell?
All the characteristics of a cell depend on the molecules it contains. A moleculeis defined as a cluster of atoms held together by covalent bonds; here electrons are shared between atoms to complete the outer shells, rather than being transferred between them. In the simplest possible molecule—a molecule of hydrogen (H2)—two H atoms, each with a single electron, share two electrons, which is the number required to fill the first shell. These shared electrons form a cloud of negative charge that is densest between the two positively charged nuclei and helps to hold them together, in opposition to the mutual repulsion between like charges that would otherwise force them apart. The attractive and repulsive forces are in balance when the nuclei are separated by a characteristic distance, called the bond length.
What determines how atoms interact?
The Outermost Electrons Determine How Atoms Interact
How many elements are there in an organism?
There are 92 naturally occurring elements, each differing from the others in the number of protons and electrons in its atoms. Living organisms, however, are made of only a small selection of these elements, four of which—carbon (C), hydrogen (H), nitrogen (N), and oxygen (O)—make up 96.5% of an organism's weight. This composition differs markedly from that of the nonliving inorganic environment (Figure 2-3) and is evidence of a distinctive type of chemistry. The most common elements in living organisms are listed in Table 2-1with some of their atomic characteristics.
What are the elements that make up matter?
Matter is made of combinations of elements—substances such as hydrogen or carbon that cannot be broken down or converted into other substances by chemical means. The smallest particle of an element that still retains its distinctive chemical properties is an atom. However, the characteristics of substances other than pure elements—including the materials from which living cells are made—depend on the way their atoms are linked together in groups to form molecules. In order to understand how living organisms are built from inanimate matter, therefore, it is crucial to know how all of the chemical bonds that hold atoms together in molecules are formed.
How do neutrons contribute to the structure of an atom?
Neutronsare uncharged subatomic particles of essentially the same mass as protons. They contribute to the structural stability of the nucleus —if there are too many or too few, the nucleus may disintegrate by radioactive decay—but they do not alter the chemical properties of the atom. Thus an element can exist in several physically distinguishable but chemically identical forms, called isotopes, each isotopehaving a different number of neutrons but the same number of protons. Multiple isotopes of almost all the elements occur naturally, including some that are unstable. For example, while most carbon on Earth exists as the stable isotope carbon 12, with six protons and six neutrons, there are also small amounts of an unstable isotope, the radioactive carbon 14, whose atoms have six protons and eight neutrons. Carbon 14 undergoes radioactive decay at a slow but steady rate. This forms the basis for a technique known as carbon 14 dating, which is used in archaeology to determine the time of origin of organic materials.
Why are Na+ and Cl-attracted to each other?
Because of their opposite charges, Na+and Cl-are attracted to each other and are thereby held together in an ionic bond. A salt crystal contains astronomical numbers of Na+and Cl-(about 2 × 1019ions of each type in a crystal 1 mm across) packed together in a precise three-dimensional array with their opposite charges exactly balanced (Figure 2-6). Substances such as NaCl, which are held together solely by ionic bonds, are generally called saltsrather than molecules. Ionic bonds are just one of several types of noncovalent bondsthat can exist between atoms, and we shall meet other examples.
