What converts chemical energy into energy the cell can use?
Cellular respiration
Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism.
Which organelle converts the chemical energy in food into a form the cells can use?
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.
What organisms can convert chemical energy into food?
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
How do we convert energy from food?
This energy comes from the food we eat. Our bodies digest the food we eat by mixing it with fluids (acids and enzymes) in the stomach. When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose.
How is chemical energy in food transformed during respiration?
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Which organelle converts the chemical energy in food into ATP?
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 do vacuoles do?
A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
What is converted to chemical energy during photosynthesis?
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Which organelle converts energy to a usable form?
How is chemical energy transformed?
Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. The chemical energy in food is converted by the body into mechanical energy and heat. The chemical energy in coal is converted into electrical energy at a power plant.
How do cells derive energy from the food we eat?
The food that we eat is broken down into simpler chemicals and the cells end up with glucose molecules. They use these glucose molecules to generate energy through a process known as cellular respiration.
Why do cells need energy from food?
The food that a cell needs is glucose. This glucose breaks down into energy type called Adenosine tri phosphate or ATP. Glucose is broken down to produce energy in the mitochondria as ATP molecules. Cells need energy to keep up life in us.
Which organelle turns food into energy for cells?
The mitochondrion is also an organelle that is a modified double unit membrane. Its purpose in the cell is very important, this organelle turns food into energy. Like turning glucose and oxygen into ATP, water, and carbon dioxide.
What process converts nutrients into energy in cells?
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the
