Respiration key terms

cellular respiration

The process by which cells convert glucose and oxygen into energy, carbon dioxide, and water, occurring continuously in living cells.

exothermic reaction

A chemical reaction that releases energy in the form of heat, such as cellular respiration.

respiration

The biochemical process in which cells convert glucose and oxygen into energy, carbon dioxide, and water.

energy transfer

The process by which energy produced during respiration is utilized for various living processes such as growth, movement, and maintaining body temperature.

Aerobic respiration

In Aerobic and anaerobic respiration, Aerobic respiration refers to a type of respiration that requires oxygen to produce energy from glucose. This matters in Respiration because it supports the learning objective to explain that respiration can take place aerobically using oxygen or anaerobically without oxygen. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

Anaerobic respiration

A type of respiration that occurs without oxygen, resulting in the production of energy and by-products such as lactic acid or ethanol.

Aerobic respiration

A type of respiration that requires oxygen to produce energy from glucose, resulting in carbon dioxide and water as byproducts.

Anaerobic respiration

A type of respiration that occurs without oxygen, producing energy from glucose and resulting in byproducts such as lactic acid or ethanol and carbon dioxide.

aerobic respiration

A type of respiration that requires oxygen and produces carbon dioxide and water as by-products, along with a high yield of energy.

anaerobic respiration

A type of respiration that occurs without oxygen, resulting in the production of lactic acid in animals or ethanol and carbon dioxide in plants and yeast, along with a lower yield of energy.

Aerobic respiration

A type of respiration that requires oxygen and produces a high yield of energy by fully oxidizing glucose.

Anaerobic respiration

A type of respiration that occurs without oxygen, resulting in lower energy yield and the production of by-products such as lactic acid or ethanol.

energy

In Aerobic and anaerobic respiration, energy refers to the capacity to do work, which organisms need for various chemical reactions. This matters in Respiration because it supports the learning objective to state that organisms need energy for chemical reactions that build larger molecules. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

chemical reactions

Processes that involve the transformation of substances, necessary for building larger molecules in organisms.

energy

In Aerobic and anaerobic respiration, energy refers to the capacity to do work, which organisms require for movement and other vital processes. This matters in Respiration because it supports the learning objective to state that organisms need energy for movement. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.

movement

The act of changing physical location or position, which requires energy provided by respiration.

energy

The capacity to do work or produce change, essential for maintaining body functions and processes.

homeostasis

The process by which organisms regulate their internal environment to maintain stable conditions, including temperature.

aerobic respiration

The process of cellular respiration that requires oxygen to convert glucose into carbon dioxide and water, releasing energy.

word equation

A representation of a chemical reaction using the names of the reactants and products, such as 'glucose plus oxygen makes carbon dioxide plus water' for aerobic respiration.

Chemical symbols

Symbols used to represent elements and compounds, such as C6H12O6 for glucose, O2 for oxygen, CO2 for carbon dioxide, and H2O for water in the context of aerobic respiration.

Aerobic respiration equation

The representation of aerobic respiration as a chemical reaction, specifically glucose plus oxygen produces carbon dioxide plus water.

Anaerobic respiration

A type of respiration that occurs without oxygen, resulting in the conversion of glucose to lactic acid in muscles.

Lactic acid

A product of anaerobic respiration in muscles, which can lead to muscle fatigue and is associated with oxygen debt.

incomplete oxidation

The process in anaerobic respiration where glucose is not fully broken down, resulting in less energy being released compared to aerobic respiration.

energy transfer

The movement of energy from glucose during respiration, which is significantly lower in anaerobic respiration than in aerobic respiration.

Anaerobic respiration

A type of respiration that occurs without oxygen, resulting in the production of ethanol and carbon dioxide in yeast and plants.

Word equation

A representation of a chemical reaction using words, such as 'glucose makes ethanol plus carbon dioxide' for anaerobic respiration.

fermentation

A metabolic process that converts sugar to acids, gases, or alcohol in the absence of oxygen, commonly used in the production of bread and alcoholic beverages.

anaerobic respiration

A type of respiration that occurs without oxygen, resulting in the production of energy and byproducts such as lactic acid in animals or ethanol and carbon dioxide in yeast.
