Are bacteria easier to observe on a plate or in a broth? How do the bacteria look in the plate compared to the broth?

prisoha [69]

Bacteria are easier to observe on a plate. The bacteria look in the plate compared to the broth as with very clear morphological structures including margin and elevation point.

On a plate as opposed to in a broth, bacteria are easier to see. While it is simpler to observe bacteria in a clear container and we are able to see their morphology (size, shape, elevation, and margin), when looking at bacteria in broth, we can only tell if the bacteria is turbid or if there is flocculent microbial growth at the bottom of the nutrient broth tube.

A unique bacterial cell or group that has repeatedly split is represented by each separate colony. Because they were kept together, the resultant cells have amassed to create a noticeable area. Most bacterial colonies are often round in form and appear white or creamy yellow in color.

Which describes the process of fermentation?

pav-90 [236]

Explanation:

<u>anaerobic process that restores NAD+ supply</u>

<u></u>

Within cells, aerobic respiration may not occur due to several factors:

- a lack of inorganic, final electron acceptors
-incomplete or lack of a complete electron transport system
-missing genes for enzymes within the Kreb's cycle

Thus, they utilize other means for the generation of energy in the form of ATP and to replenish NAD+ an oxidized form of NADH, the main electron carrier in glycolysis. Pyruvate is produced in the cytoplasm via glycolysis- it is also used as an electron acceptor in a process called fermentation.

Further Explanation:

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)
The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.
