ATP, or adenosine tri-phosphate, is utilized as an energy source by causing confirmational (shape) changes. One of the phosphate groups is stripped off and bound to the molecule that needs the energy, causing a shape change (usually in a direction that the work is needed to be done). This is accomplished until the desired work is complete, the now ADP (adenosine di-phosphate) is recycled and given a third phosphate group again so that it can be re-used later.
What else can I help you with?
What is the cellular movement of a substance that requires the use of energy.?
Active transport is the cellular movement of a substance that requires the use of energy. This process involves the movement of molecules across a cell membrane against their concentration gradient, requiring the cell to expend energy in the form of ATP. Active transport allows cells to control the internal environment and maintain homeostasis.
What kind of energy is used in walking?
Walking primarily uses mechanical energy, which is the energy associated with the movement and position of an object. This energy comes from the chemical energy stored in our bodies, particularly in the form of glucose, which is broken down to produce the necessary energy for muscle movement.
What is energy free movement of materials through a cell membrane?
Energy-free movement of materials through a cell membrane is called passive transport. This process includes diffusion, osmosis, and facilitated diffusion, where molecules move from an area of high concentration to an area of low concentration without the input of energy.
The direct source of energy in the cell?
The direct source of energy in a cell is adenosine triphosphate (ATP). ATP is produced through cellular respiration, which converts nutrients from food into a form of energy that the cell can use to carry out its functions. ATP releases energy when its phosphate bonds are broken, providing the necessary energy for cellular processes.
What does movement energy mean?
Movement energy refers to the kinetic energy generated when an object is in motion. It is the energy associated with the movement of an object due to its velocity. Movement energy can be converted into other forms of energy, such as thermal or potential energy.
What is a single that has all of the items necessary to carry out life's activities?
A molecule of adenosine triphosphate (ATP) carries the chemical energy necessary for cell functions and life activities. It acts as a universal energy currency in cells, powering various processes like metabolism, growth, and movement.
The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
What is the use of energy to bring necessary materials into cell?
The same use of energy that is used to bring necessary materials into a cell.
What is the movement of across the cell membrane using cell energy?
This type of movement is called simple diffusion.
How is mechanical energy exhibited by a cell?
by cellular movement or cell growth
What is the movement of materials through a cell using cellular energy?
cell
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does facilitated transport require energy for the movement of molecules across the cell membrane?
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
Which component is necessary in an electrolytic cell but not in a voltaic cell?
An electrolytic cell requires an external power source to drive the non-spontaneous redox reactions, while a voltaic cell generates its own electrical energy from spontaneous reactions. This external power source is essential for the electrolytic cell to function, as it facilitates the movement of electrons and ions necessary for the electrolysis process. In contrast, a voltaic cell operates independently without needing an external energy input.
What is A cell moving particles with the use of energy is called?
Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
Why is mitochondria necessary to cell life?
Mitochondria is like energy capsules for the cell and cells need plenty of energy to do what they are designed to do.
What is the movement of substances through a cell membrane without the use of cell energy?
passive transport
