What else can I help you with?
Does cellular respiration happen in humans?
Yes, cellular respiration occurs in humans. Life depends on this process in order to create enough energy to run all cellular activites that allow us to function.
What is the process of breaking down food by an organism when there is not enough oxygen present?
Anerobic respiration
What process of cellular respiration causes muscle soreness?
When the body produces lactic acid because it doesn't have enough oxygen this makes a muscle sore.
When does cellular respiration happens?
It happens all of the time, except when you are sprinting. It then switches to fermentation, which doesn't use oxygen. This is because when you are sprinting, you don't get enough oxygen for cellular respiration to occur.
What process do cells use when they do not have enough oxygen for respiration?
Cells use a process called anaerobic respiration or fermentation when they do not have enough oxygen for respiration. This process allows for the production of energy in the absence of oxygen, but it is less efficient than aerobic respiration. It usually produces lactic acid or ethanol as byproducts.
Why is oxygen essential?
Oxygen is essential for aerobic cellular respiration, the process by which cells get energy from food. If we are deprived of oxygen, aerobic respiration will cease, and we will not be able to get enough energy to survive.
What is the specific cellular process that would be affected by a glucose shortage?
Glycolysis, the process by which glucose is broken down to produce energy in the form of ATP, would be directly affected by a glucose shortage. Without enough glucose, cells would not be able to efficiently generate energy, impacting many essential cellular functions.
Why is respiration important to organic organism?
Most life uses the chemical process of oxidation to obtain the chemical energy needed to run cellular activities and synthesize other molecules. The oxygen for this process is obtained from the air via respiration.
How might an organism benefit by carrying Out fermentation instead of cellular respiration?
Organisms prefer cellular respiration over fermentation.Cellular respiration gains a cell 38ATP molecules per every glucose molecule.Fermentation only gains 2ATP per glucose molecule.Obviously, you can see the difference. Cellular respiration provides much more energy for the cell, and this is why they prefer this over fermentation.There are organisms like facultative anaerobes that can preform either process, but they do cellular respiration if oxygen is available. These organisms only preform fermentation if they are in an "oxygen debt." (Like when you run, you are using a lot of energy, and you cannot get enough oxygen for cellular respiration. You are in "oxygen debt," and your muscle cells start doing fermentation. But your muscle cells prefer using aerobic reparation (cellular respiration) so you start panting. Once you get your breath back, oxygen is restored and your cells again preform cellular respiration and get more energy faster.)However, there are still obligate anaerobes that are poisoned by oxygen, and only use fermentation.Hope this helped!!
Does cellular respiration use oxygen?
C6H12O6 + 6O2 + 6H2O -----> 6CO2 + 12H2O + energyEasier:glucose (sugar) molecules + oxygen molecules = carbon dioxide molecules, water molcules, and energy**Oxygen is used to create energy in cellular respiration**(CO2 and H2O are waste products)Source:7th grade science class
Why is it important where cellular respiration occurs?
In human lungs. Because lungs is the only part where cellular respiration takes. This is the only part that helps in take in oxygen, utilize it to other parts and then give off Carbon Dioxide.
Why the body switches between cellular and anaerobic respiration?
The body needs oxygen for cellular respiration. When doing strenuous activity, such as lifting weights, the mitochondria cannot get enough oxygen. Without oxygen to act as an electron receptor, the body creates lactic acid to "reset" coenzymes to continue respiration.
