What energy conversion happens when animals use respiration?
Glucose + oxygen gas -> carbon dioxide + water + energy
What happens when wood in a campfire burns?
The cellulose in wood is made up of glucose molecules. In combustion (burning), oxygen gas combines with the glucose (C6H12O6), breaking it apart into H2O and CO2, which are released as gases. Additionally, water that's already present, as well as other components, are vaporized by the heat of combustion, and released.
What substances react in aerobic respiration and where do they come from?
Glucose and oxygen are the reactants. In humans glucose comes from digested food, and oxygen is breathed in from the air. In plants, glucose is made in photosynthesis, and oxygen diffuses in from the air.
What 3 elements chemically combine to form glucose?
The three elements that make up glucose are carbon, hydrogen and oxygen. These can be in the form of carbohydrates or sugars.
What burns sugar with oxygen?
glucose
Why do yeast cells consume glucose much more slowly if oxygen is present than absent?
why do yeast cells consume glucose much more slowly when oxygen is present than when oxygen is absent
What happens when a glucose and oxygen molecules meet?
they react
Is respiration the metabolism of glucose when oxygen is present?
yes, cellular respiration
What happens if oxygen is not present?
you will die
What happens to accumulated lactic acid when oxygen is present?
Lactic acid diffuses into the bloodstream, and carried to the liver. Here, it's converted back into glucose, but in order to do this, extra energy is required, and as such extra oxygen is needed.
What is the metabolism of glucose when oxygen is present is called?
It's called "Aerobic Metabolism"
What is the metabolism of the glucose when oxygen is present called?
It's called "Aerobic Metabolism"
What is the element in glucose?
glucose is a carbohydrate. it is made up of carbon chain and and an aldehyde group attached to the end carbon. the other carbons have hydrowyl groups attached to themcarbon, hydrogen, oxygen
What happens when oxygen is present after glycolysis?
fermentation
Can cellular respiration and fermentation be used to release energy?
No. Either cellular repsiration or fermentation can be used to release energy depending on the presence or absense of oxygen. When oxygen is present, it acts as the terminal electron acceptor in cellular repritation, followed by the release of energy When there is no oxygen present, other organic molecules (like lactic acid) accept the terninal electron and energy is generated
What happens when oxygen is combines with sugar inside every cell?
It creates glucose.
What are 2 reactants of cellular respiration?
Oxygen and Glucose =P
