How has the electron microscope increased our understanding of the cell?
Electron microscopes have higher resolution than light microscopes, allowing us to see cellular structures in much greater detail. This has helped scientists discover new organelles, study cellular processes at the molecular level, and understand the ultrastructure of cells, leading to advances in cell biology and medical research.
Can a cell produce ATP in the absence of Oxygen?
Oxygen is required for ATP generation. However, that oxygen need not be in elemental form. Many organisms can obtain oxygen by breaking down oxygen-containing chemicals, like sugars and alcohols.
Efficiency of a respiration pathway refers to the?
Efficiency of a respiration pathway refers to the amount of energy produced by the pathway relative to the amount of energy input. A highly efficient pathway will produce more ATP (energy) per unit of substrate consumed, resulting in greater energy yield for the organism.
What are some of the advantages of viewing cells under high power?
Viewing cells under high power allows for greater magnification and resolution, which can help in observing fine cellular structures and details. This can provide a better understanding of cell morphology and organization, as well as identification of cellular components such as organelles. High power magnification can also aid in studying cell processes and interactions more closely.
What is the significance folds of inner membrane of mitochondria?
The folds in the inner membrane of the mitochondria are called cristae. They serve to provide a greater surface area for the proton-pump through which protons pass down their concentration gradient through ATP synthase to produce ATP in cellular respiration.
Do adults have a greater risk of becoming an alcoholic than teenagers?

What is the difference in the VO2 Max between men and women?
genetically males have a higher VO2 max that females because males have a greater muscle mass that females. Mitochondria are the site of cellular respiration and the majority of them are located within muscle tissues in the body. If there are more sites for cellular respiration than the body will be able to keep at an aerobic level of fitness for longer because the body can remove a higher volume of oxygen from the bloodstream. This would cause a person to maintain a longer state of aerobic respiration and therefore have a higher VO2 max.
What do the cristae do for the mitochondria?
The folds of inner membrane of mitochondria are called cristae (singular: crista). Crista increases the surface area of mitochondria. Most of the biochemical work of mitochondria is done on the cristae.
How many times greater is the How many times greater is the ATP production by respiration than by fermentation?
A.T.P. production by respiration is greater than fermentation because most of the energy remains locked up in the products of fermentation (alcohol of lactic acid) formed from pyruvic acid.
What does burning fossil fuels and cellular respiration have in common?
Both release carbon into the atmosphere, but burning fossil fuels releases CO2 at a much greater amount. Both cellular respiration and combustion require a core fuel for the process to happen at all. This fuel is stored energy, and the entire process of combustion or respiration is to convert that energy from its stored state -- in the fuel -- to another state that the engine, either mechanical or bionic, can use to power its other operations. While fossil fuels and sugar molecules have very different structures, they both have a series of molecular bonds that the energy harvesting process will break apart.
What does oxygen produce in cells?
Oxygen doesn't produce anything. It is vitally important in the electron transport chain of the mitochondria as an electron acceptor than then binds with two hydrogens to make water so that ATP can be produced in a greater quantity than by glycolysis alone.
Does our body cells always use cellular respiration to break down glucose explain?
Only when your body cells run out of energy.
Can white wine be the cause of hemophilia or help it on?
No alcoholic beverage can cause hemophilia. To the contrary, the moderate consumption of alcoholic beverages (beer, wine and liquor) is associated with better health and greater longevity than is abstaining or abusing alcohol.
What is abdominothoracic respiration?
Abdominothoracic respiration is the type of respiration dominant in males.In this type of respiration the muscles of stomach and diaphragm play a greater part than the thoracic muscles.The dominant respiration in females is thoracoabdominal respiration in which thoracic muscles are dominant.It is speculated the thoracoabdominal respiration(IN WHICH ABDOMINAL MUSCLES ARE USED LESS THAN THORACIC MUSCLES)help women in maintaing the respiratory movements in pregnancy when a great volume of abdomen is used up by the fetus.
How can you breathe out more CO2?
Yes. You exhale carbon dioxide and oxygen. You breathe out normal air although the cabon dioxide level is greater and there is less oxygen.
Is smirnoff vodka bad for your body?
Drinking any alcoholic beverage in moderation promotes good cardiovascular health in particular and good overall health in general. It also promotes greater longevity. However, abusing any alcoholic beverage is to be avoided and can have negative health and safety consequences. That's bad for your body.
What organelle has increased in density in the cytoplasm of muscles that are being exercised in response to a greater demand for ATP production?
The mitochondria increase in density in the cytoplasm of muscles that are being exercised due to the increased demand for ATP production. Mitochondria are the primary organelles responsible for producing ATP through cellular respiration, and an increase in their density helps meet the energy needs of the active muscle cells.
