Respiration vs. Combustion — What's the Difference?

The process by which cells obtain energy from glucose.

Reaction where a fuel burns completely using ample oxygen, producing CO2 and water.

Respiration using oxygen to break down glucose.

A reaction that releases heat.

Energy production in the absence of oxygen.

The visible part of a combustion reaction.

Part of respiration where ATP is formed.

Reaction where oxygen is limited, producing carbon monoxide and soot.

The initial step of glucose breakdown in respiration.

The minimum temperature required to initiate combustion.

The action or process of inhaling and exhaling; breathing. Also called ventilation.

Combustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Combustion does not always result in fire, because a flame is only visible when substances undergoing combustion vapourise, but when it does, a flame is a characteristic indicator of the reaction.

An act of inhaling and exhaling; a breath.

The process of burning.

The action or process by which an organism without lungs, such as a fish or plant, exchanges gases with its environment.

A heat-producing chemical reaction in which a fuel combines with oxygen or with some other substance that behaves chemically like oxygen.

The oxidative process occurring within living cells by which the chemical energy of organic molecules is converted in a series of metabolic steps into usable energy in the form of ATP, involving the consumption of oxygen and the production of carbon dioxide and water as byproducts.

Violent anger or agitation

Any of various analogous metabolic processes by which certain organisms, such as anaerobic bacteria and some fungi, obtain energy from organic molecules without consuming oxygen.

(chemistry) The act or process of burning.

The process of inhaling and exhaling; breathing, breath.

A process whereby two chemicals are combined to produce heat.

An act of breathing; a breath.

A process wherein a fuel is combined with oxygen, usually at high temperature, releasing heat.

Any similar process in an organism that lacks lungs that exchanges gases with its environment.

(figuratively) Violent agitation, tumult.

The process by which cells obtain chemical energy by the consumption of oxygen and the release of carbon dioxide.

The state of burning.

The act of respiring or breathing again, or catching one's breath.

The combination of a combustible with a supporter of combustion, producing heat, and sometimes both light and heat.

Relief from toil or suffering: rest.

Violent agitation; confusion; tumult.

Interval; intermission.

A process in which a substance reacts with oxygen to give heat and light

The act of resping or breathing; the act of taking in and giving out air; the aggregate of those processes bu which oxygen is introduced into the system, and carbon dioxide, or carbonic acid, removed.

A state of violent disturbance and excitement;

A single complete act of breathing in and out;

The act of burning something;

The bodily process of inhalation and exhalation; the process of taking in oxygen from inhaled air and releasing carbon dioxide by exhalation

Anaerobic respiration does not use oxygen and produces less energy compared to aerobic respiration, which uses oxygen.

The mitochondria is the main site of respiration in eukaryotic cells.

ATP is the primary energy molecule produced during respiration.

Combustion can be hazardous due to its potential to release harmful pollutants and its uncontrolled nature.

No, respiration is a fundamental process in almost all living organisms, including plants and microbes.

Combustion requires oxygen to initiate and sustain the reaction.

Common fuels include natural gas, coal, wood, and gasoline.

Respiration's byproducts, like CO2, are utilized in photosynthesis, helping balance atmospheric gases.

Combustion can lead to air pollution, global warming, and environmental degradation.

ATP releases energy when its phosphate bonds are broken.

Incomplete combustion can produce carbon monoxide, a toxic gas, posing serious health risks.

Higher temperatures can increase the rate of respiration up to a point beyond which it can inhibit or damage cellular structures.

Factors such as temperature, oxygen availability, and fuel type affect the rate of combustion.

Yes, combustion is commonly used for propulsion in internal combustion engines and rockets.

Cellular respiration is highly efficient, converting about 34% of the energy in glucose into ATP.
