What do cells with high energy requirements have?
In ATP the energy is stored in the form of chemical bonds. In cells where there is a high energy demand large numbers of mitochondria are found. The tail of a sperm contains many mitochondria and they run in a spiral like form along the length of the tail.
What cell has high energy?
Mitochondria
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What provides energy to cells?
ATP is the molecule that provides energy for cells in daily processes. It is produced from respiration in the mitochondria.
Is the high energy molecule used to power cellular work?
ATP is a high energy molecule, with energy stored in the bond for the third phosphate group. It takes energy to produce an ATP from ADP and a phosphate group so this is an endergonic reaction. ATP is the energy currency of the cell. The energy released in the break down of ATP is used to power many cellular activities.
Do cells with greater energy requirement have more mitochondria than cells with lower energy requirements?
Logically, mitochondria multiply when a the energy needs of a cell increase. Therefore, power-hungry cells have more mitochondria than cells with lower energy needs. For example, repeatedly stimulating a muscle cell will spur the production of more mitochondria in that cell, to keep up with energy demand.
Which type of cells have a high concentration of mitochondria?
In keeping with our theme of form following function, it is important to point out that muscle cells have a very high concentration of mitochondria that produce ATP. Your muscle cells need a lot of energy to keep your body moving.
Is the powerhouse of cell?
Mitochondria: The Powerhouse of the Cell.
What high energy molecules are formed by the ETC?
Electron transport chain (ETC): Using the NADH and FADH2 molecules formed during Glycolysis and Krebs Cycle, the electron transport chain creates a proton gradient that ultimately leads to the production of about 32 molecules of ATP. The ETC takes place in the mitochondrial matrix and requires oxygen.
Which molecule has higher energy ADP or ATP?
Thus, ATP is the higher energy form (the recharged battery) while ADP is the lower energy form (the used battery).
Which of the following is a high energy molecule that is a product of cellular respiration?
adenosine triphosphate (ATP)
One objective of the degradation of foodstuffs is to convert the energy contained in chemical bonds into the energy-rich compound adenosine triphosphate (ATP), which captures the chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
Which type of cells have a high concentration of mitochondria quizlet?
The 12 hydrogen atoms that form glucose originally came from _____ molecules. Cardiac muscle cells have a higher concentration of mitochondria than skeletal muscle cells.
Do heart cells have a high concentration of mitochondria?
There are more mitochondria found in heart cells because this means we are able to produce enough energy to keep it functioning efficiently.
How do cells acquire energy?
How do cells acquire energy? By breaking down high energy molecules in or food. For example: when we eat carbohydrates: Digestion breaks these complex sugars down to glucose.
What is the most abundant energy carrier molecule in a cell?
Adenosine 5′-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.
What are the benefits of fuel cells?
Fuel cells have several benefits over conventional combustion-based technologies currently used in many power plants and passenger vehicles. Fuel cells can operate at higher efficiencies than combustion engines, and can convert the chemical energy in the fuel to electrical energy with efficiencies of up to 60%.
How do all cells make ATP?
All cells make ATP by pathways that release chemical energy from organic compounds such as glucose. Cells store chemical energy as ATP to use in future reactions that require energy input.
