With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to

introduce them to the idea that the cell wall can also act as a foundation to build things upon. Bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. For example, flagella are long, whiplike protein structures that are used by many Gram-positive and Gram-negative bacteria for locomotion. In order to function effectively, a flagellum must be firmly anchored to the cell wall. How will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? With a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use ATP power to spin the hook and the flagella attached to it. Bacterial flagella have a biological motor that spins within the cell wall and is powered by ATP. This allows the flagella to spin in a whiplike motion to propel the bacterium.

Bacterial flagellum is composed of protein flagellum which looks like hollow tube. It passes through protein rings (basal body rings) in the cell's membrane that act as bearings. Flagellum is long, filamentous and it rotates via motor which is located on the inner cell membrane. The motor is powered by proton motive force (flow of protons through the membrane due to a concentration gradient).

In a second experiment, variety A seedlings at both temperatures were treated with a chemical that prevents NADH from being oxid
Paraphin [41]

Answer:

No metabolism occur and decrease oxygen consumption.

Explanation:

There is adverse effect of chemical on metabolism and oxygen consumption of the treated seedlings because NADH is very important because it maintains the hydrogen pumping that produces ATP molecules. If NADH is oxidized to NAD, then the metabolism did not occur in the seedlings and due to no metabolism, oxygen consumption is also greatly affected.

Which is not something that occurs in translation? A codon and an anticodon pair. A peptide bond is created. A molecule of mRNA
Veseljchak [2.6K]

Answer:

A molecule of mRNA is formed.

Explanation:

Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.

The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.

The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.

Note: A molecule of mRNA is formed during transcription

What can be done to reduce the production of carbon dioxide?.
Phantasy [73]

Answer:

Probably not much.

We exhale carbon dioxide every second.

"Burn less trees." - thank you kaliliew16

Therefore, not much can be done.. We would have to all stop breathing to stop the flow of carbon dioxide, meaning we'd all die off quickly due to lack of oxygen.

hope it helps you!
