Answer:
The basic processes of cellular respiration are: glycolysis, followed by Krebs cycle, the electron transport chain and chemiosmosis.
Explanation:
This task asks one to arrange the basic processes of cellular respiration in the correct order.
Place the major steps of cellular respiration in order by dragging the appropriate figure to each box.
Cellular Activity 1. Glycolysis pathway- The reaction starts with glucose. In the process, glucose is oxidized and split into two 3-carbon compounds. The byproducts is 2 ATP, 2 NADH, and 2 molecules ofpyruvate.
Cellular Activity 2. Krebs cycle- The Krebs cycle follows glycolysis, its an aerobic process but before the glycolysis end-product enters the Krebs cycle, it must first undergo loss of CO2, oxidation, and attachment to coenzyme A to form acetyl CoA.
Cellular Activity 3. Electron transport chain and chemiosmosis pathway- Here we observe that electron carriers such as NADH and FADH2 that are carrying electrons are removed during oxidation steps gets to the electron transport chain and loss their electrons to the chain.
As electrons move along the chain, the energy they lose as they are sequentially made accessible to lower-level electron carriers and electrons eventually to the final electron acceptor is clipped for ATP production.
New cells come from old cells
The answer would be A hope it helps
Water would flow out of them because they are hypotonic to the external environment. b. water would flow into them because they are hypotonic to the external environment.
Answer:
The right answer is Letter A
Explanation:
The proposed model for the mechanism of initial transcription that suggests the entire RNA polymerase enzyme moves along the DNA is <em>transient-excursion model</em>, and the proposed model that is best supported by experimental findings is<em> scrunching model.</em>
<em>Because RNA polymerase leaves the promoter, translocate a short way along DNA template, synthesizes a short transcript before aborting transcript, releasing the transcript and returning to its original location on promoter. That is the transient-excursion model.</em>
<em>The scrunching model downstream DNA is pulled into the enzyme and has accumulated within the enzyme as single stranded bulges.</em>
<em>Experiments show that scrunching is right, experiments using single molecule analyses that allow the positions of different parts of polymerase to be measured relative to each other and to the template DNA during transcription.</em>
