What can electron microscopes make visible that light microscopes can not?

1 answer:

5 0

Electron microscopes therefore allow for the visualization of structures that would normally be not visible by optical microscopy. Light microscopes are not able to see things in a larger magnification compared to electron microscopes. Also you're able to see in 3d in electron microscopes and you can't see in 3dimentsional in light microscopes.

The bacterium E. coli is capable of performing aerobic respiration, anaerobic respiration, and fermentation. When would it perfo

Eduardwww [97]

Answer:

1. Aerobic respiration: when oxygen is present.

ATP is made by respiratory linked phosphorylation.

2. Anaerobic respiration: when oxygen is absent. For example, in the gut of mammals.

ATP is made by substrate-level phosphorylation.

3. Fermentation: this is the last resort or least preferred process after aerobic and anaerobic respiration, respectively. This is achieved in conditions of oxygen absence (anaerobic conditions) and when energy (ATP) is not required in high levels.

ATP is made by substrate-level phosphorylation.

Explanation:

Escherichia coli is a Gram-negative species of versatile bacterium that is not only able to grow when oxygen is present (aerobic conditions), but it can also adapt to different conditions and grow in the absence of oxygen using either anaerobic respiration or fermentation. This is a great adaptation because it allows it to grow in a wide variety of environments.

1. Aerobic respiration: when oxygen is present. It is the most preferred mechanism to produce ATP as conditions are optimal.

ATP is made by respiratory linked phosphorylation.

*Metabolism releases energy and is captured by the phosphate bonds of ATP.

2. Anaerobic respiration: when oxygen is absent. For example, in the gut of mammals. The second preferred mechanism to produce energy because it does not produce as much energy as aerobic respiration does.

ATP is generated by substrate phosphorylation.

*Phosphate groups are directly transferred during the conversion of ADP into ATP.

3. Fermentation: this is the last resort or least preferred process after aerobic and anaerobic respiration, respectively, because it produces even less ATP. This is achieved in conditions of oxygen absence (anaerobic conditions) and when energy (ATP) is not required in high levels.

ATP is made by substrate-level phosphorylation.

*Phosphate groups are directly transferred during the conversion of ADP into ATP.

What does temperature determine about a star?

-Dominant- [34]

If a star is a brilliant blue color, it's really hot and emits a lot of energy. If it's red, it has a cool surface temperature instead. Therefore, the dominant wavelength of a star's light can tell us its surface temperature.

ASAP How do products of photosynthesis compare to the reactants of respiration?

Lemur [1.5K]

Answer:

Explanation:

Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.

the letters A, T, C, and G get highlighted in the people’s names. DESCRIBE the significance of these letters.

rjkz [21]

Answer:

Explanation:

If you are talking abou the movie GATTACA, then the reason is that A, T, G, and C are DNA coding letters so it would sort of make sense to highlight those to complement or enhance the movie's meaning (its also part of the movie's name)
