Why can you not use oxygen in compounds to breathe?
Our metabolisms take advantage of a reaction between oxygen gas and compounds such as glucose to release energy. Oxygen compounds do not contain the same energy and do not react in quite the same way with other substances, so we cannot use them. Most substances that are as reactive as oxygen are toxic, but we have adapted specifically to be able to use oxygen.
What is the primary source of oxygen?
Plants: they take in CO2 during photosynthesis and give off oxygen. The rainforests are a major help, but are being cut down at very fast rates.
How do plants change gases?
Leafs take carbon dioxied ane convert in oxygen by photosynthesis process with help of water,sunlight
How is oxygen replenished in nature?
Plants take in carbon dioxide then when they take that they give off oxygen
Do virus take any oxygen?
No, viruses do not require oxygen.
Cells take in oxygen by simple diffusion and glucose by facilitated diffusion Therefore oxygen uptake and glucose uptake will differ from each other in all respects except what?
the need for ATP ANSWER Facilitated diffusion and diffusion do differ in ATP requirments
Where does the reaction between glucose oxygen take place?
The reaction between glucose and oxygen is not spontaneous. This can be demonstrated by a container of glucose sitting on a shelf, not oxidizing.
What processes can take place in a root hair cell when oxygen is not available?
active transport and osmosis
What do plants take in through tiny holes in their leaves that help them to make food?
They take in Carbon Dioxide which is combined with water and energy from the sun to create sugar (glucose) and oxygen.
What other substance is needed for respiration to take place?
glucose and oxygen
What gases are exchanged during transpiration?
Carbon dioxide and oxygen. It gets oxygen from the sun and they get glucose. then, they break the glucose down and gives out carbon dioxide.
Example of diffusion inside the human body?
The lungs utilize diffusion to transfer oxygen into the blood stream and take the CO2 out. Another example is the oxygen gradient set up in the ATP transfer cycle.
How are gases exchanged in both sponges and cnidarians?
Cnidaria don't have gills or lungs, but they take in oxygen from surrounding water through diffusion.
How does the exchange of nutrients and oxygen with waste and cardon dioxide take place in the capillaries?
Its all diffusion.
What do the chloroplast take in and what do they produce?
CO2 and water is taken in . Glucose and oxygen is released
What two things do you need for aerobic respiration to take place?
Glucose and Oxygen
Which gas is required for cellular respiration to occur?
Cellulr respiration requires glucose and oxygen and produces carbon dioxide, water and energy
