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 <u>respiratory linked phosphorylation</u>.

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

ATP is made by <u>substrate-level phosphorylation</u>.

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 <u>substrate-level phosphorylation</u>.

Explanation:

<em>Escherichia coli </em>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: <em>when oxygen is present. It is the most preferred mechanism to produce ATP as conditions are optimal. </em>

ATP is made by <u>respiratory linked phosphorylation</u>.

<em>*Metabolism releases energy and is captured by the phosphate bonds of ATP.</em>

2. Anaerobic respiration: <em>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.</em>

ATP is generated by <u>substrate phosphorylation</u>.

<em>*Phosphate groups are directly transferred during the conversion of ADP into ATP.</em>

3. Fermentation: <em>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. </em>

ATP is made by <u>substrate-level phosphorylation</u>.

<em>*Phosphate groups are directly transferred during the conversion of ADP into ATP.</em>

9966 [12]

Answer:

The kinetic molecular theory explains the expansion of a solid material with increases of temperature as basically the result of <u>molecules moving a little farther apart.</u>

Explanation:

The kinetic-molecular theory explains the changes of state in the following way: When a solid is heated, its particles increase their kinetic energy, so that the vibration becomes more and more intense until, having reached the melting temperature, they become so weak that the particles acquire freedom of movement, that is, if we increase the temperature of a solid material system, its molecules will move faster and the average distance between them will increase, the cohesion forces decrease and there will come a time when these forces are incapable to keep the molecules in fixed positions, the molecules can move.

Nearly all plant cells and many bacteria are surrounded by a cell wall. However, the roles these walls play in cell division dif

kherson [118]

Answer:

1. FtsZ tubulin homolog

2. actin and tubulin

3. actin and tubulin

4. b. animals and bacteria

Explanation:

1. In bacteria, the binary fission process takes place when the cytoskeletal structure of the bacteria are assembled to form the contractile ring in the centre of the cell. The contractile ring in bacteria is composed of the Z-protein which is a tubulin homolog.

2. Plants: the plants divide by the cell plate formation and not the contractile ring formation. This is mediated by the actin, tubulin and vesicle produced from the dictyosomes.

3. Animals: a contractile ring attached to the plasma membrane is formed which is composed of the F-actin and tubulin.

4. Since the bacteria and animal cytokinesis involves the formation of the contractile ring and thus the same mechanism of cytokinesis.

What Are the three ways that a sedimentary rock can be changed and what is the result of each change ?

Tresset [83]

1.Heat and/or pressure 2. Weathering and erosion 3.melting. The heat and pressure will make the sedimentary rock into a metamorphic rock. The melting will make it into magma which will then cool and become igneous rock. The weathering and erosion will make the rock break down into small parts (sediments) which will stay like that for a long time and eventually become a sedimentary rock once again.
