Cells need energy to perform processes in order to sustain life. In plants, energy from the sun is needed for photosynthesis, a process which allows the plant to create glucose for food. Animals then get their energy from plants and other animals and convert this energy into ATP energy for processes like cellular respiration and protein synthesis. All these processes require energy and work together to keep the organism alive.
What else can I help you with?
Can human cells live independently outside the body without a supply of energy?
No, human cells require a constant supply of energy to stay alive. Without a supply of energy, human cells cannot perform essential functions like cell division, metabolism, or repairing damage, eventually leading to cell death.
Why is ATP considered such a good energy currency molecule?
ATP is considered a good energy currency molecule because it can easily release and transfer energy for various cellular processes. Its structure allows for quick energy release when needed, making it efficient for powering cellular activities. Additionally, ATP can be rapidly regenerated in cells, ensuring a continuous supply of energy for metabolic reactions.
Why living things need a continuous supply of energy?
All living things require a continual supply of energy in order to function. This energy is carried around our bodies within certain molecules, one of the best known being ATP*, which converts heat from the sun into a useable form for animals and plants.This ATP store is being constantly used and regenerated in cells via a process known as respiration, which is driven by natural catalysts called enzymes.
Cells store energy in adenin triphosphate or ATP molecules to maximize the productin in these molecules cells need?
Cells require nutrients such as glucose and oxygen to produce ATP efficiently through the process of cellular respiration. This process occurs in the mitochondria, where glucose is broken down to release energy that is used to convert ADP (adenosine diphosphate) into ATP. Additionally, cells rely on a series of enzyme-catalyzed reactions to facilitate the conversion of nutrients into ATP, ensuring a continuous supply of energy for various cellular functions.
Why do muscle cells and a brain cells need a lot of energy?
Muscle cells require a lot of energy for contraction and movement, while brain cells need energy for maintaining electrical activity and communication within the nervous system. Both types of cells have high energy demands due to their specialized functions and continuous activity.
Why must cells have continuous supply of energy?
If they dont have one they will die depends on the cell
Why are endergonic and exergonic reactions are said to be coupled in living cells?
Endergonic reactions absorb energy, while exergonic reactions release energy. In living cells, these reactions are coupled so that the energy released from exergonic reactions can be used to drive endergonic reactions. This coupling allows cells to maintain energy balance and perform essential functions.
Does the chemical equation of ATP release exergonic exothermic or absorb energy endergonic endothermic?
The breakdown of ATP into ADP and inorganic phosphate releases energy, making it an exergonic and exothermic reaction. This energy is used by cells for various cellular processes.
Why do animals need a continuous supply of oxygen?
Animals need a continuous supply of oxygen because it obtains energy from their food. To acquire such energy from food, cells in animals require a steady supply of ATP in order to function. To produce this ATP, cellular respiration requires oxygen. Without ATP, cells and the organism will die so therefore, animals need a continuous supply of oxygen to survive.
Why would it be beneficial to couple an exergonic reaction with an endergonic reaction?
Coupling an exergonic reaction with an endergonic reaction allows the energy released from the exergonic reaction to drive the endergonic reaction, making it energetically favorable. This coupling enables cells to carry out important processes that would not occur spontaneously due to their energy requirements.
Do carbohydrates supply energy and fiber in plant cells?
They supply energy but not fibre.
Do vitamins supply energy to cells?
no, they don't. the energy for the cells comes from the ATP.
What do single sugars supply to cells?
ENERGY
A chemical reaction such as cellular respiration that releases free energy?
glucose and other food molecules
In cells endergonic reactions are often coupled with enzymatic reactions that store energy True or false?
True. Endergonic reactions, which require energy input, are often coupled with exergonic reactions that release energy through enzymatic processes. The energy released from the exergonic reaction is used to drive the endergonic reaction forward. This coupling allows the cell to maintain energy balance and perform various functions.
What is an exergonic reaction?
Exergonic reactions indicate a negative change in Gibbs free energy, which in English means that the reactions are spontaneous and do not require addition of energy. The exchange of oxygen and carbon dioxide in blood and lungs is an example. It is the concentration gradient that runs these exchanges passively, without additional energy from the cells.
What does the mitrocondria do for cells?
These organelles supply energy for the cells metabolism. These are similar to small batteries.
