One primary advantage of light microscopy over electron microscopy is that ________. light microscopy provides higher contrast t

Alinara [238K]

Answer:

light microscopy allows the visualization of dynamic processes in living cells light

Explanation:

Light microscopy has a biggest advantage over electron microscopy because it all the visualisation or ability to observe living cells and biological activity such as the uptake of food, cell division and movement. Light microscopy can be use in-vivo staining techniques to visualise the uptake of colored pigments by the cells which cannot be observed with electron microscopy because in electron microscopy the element must be fixed, dehydrated or dead before been visualised . Electron microscope cannot observe living cells and can only observe dead or dry specimens so that electrons can pass through the specimen to be able to observe.

In an experimental situation, a student removes the 5' cap and poly-A tail from an mRNA molecule before inserting it into a euka

finlep [7]

<span>The right answer is: A
A) The molecule is digested by exonucleases because it is not protected at the 5' end. (correct)
B) The molecule is digested by restriction enzymes in the eukaryotic cell's nucleus. (false it is digested by exonucleases due to the absence of the 3'cap and the 5'tail)
C) The mRNA cannot exit the nucleus to be transcribed without the 5' cap and poly-A tail. (false, to be TRANSLATED and not to be transcribed)
D) The mRNA molecule attaches to a ribosome and is translated at a much slower rate. (false, it doesn't have a role to play in translation)</span>

Under aerobic conditions, when is pyruvate produced and consumed? It is produced in glycolysis and consumed in fermentation.It i

Nastasia [14]

1. The correct answer is: It is produced in glycolysis and consumed in the citric acid cycle

Pyruvate is a molecule that connects metabolic processes of cellular respiration: glycolysis and Krebs (citric acid) cycle. Glycolysis is a process that occurs in the cytosol of the cell and in which several of enzymes catalyze the breakdown of glucose molecules. At the end of glycolysis, products are two pyruvate molecules and released energy (ATP).

After this step, in the matrix of mitochondria oxidation of pyruvate occurs. During this reaction, pyruvate is converted into a three-carbon molecule—acetyl CoA. Acetyl then acts as fuel for the citric acid cycle.

2. The correct answer is: electron transport chain

The amount of ATP produced per glucose is:

Glycolysis: 2 ATP

A process in which glucose is converted into two molecules of pyruvate, ATP is made, NAD+ is converted into NADH.

Krebs Cycle (citric acid cycle): 2 ATP

The acetyl CoA (made from pyruvate) goes through a cycle of reactions. ATP, NADH, FADH2 and CO2 is released.

Electron Transport Chain (oxidative phosphorylation): 28 ATP

Electrons from NADH and FADH2 move down the electron transport chain, protons are pumped out of the matrix, forming a gradient. Gradient of proton is used for the ATP synthesis.

Fermentation: 2 ATP

Breaking down carbohydrates (usually glucose) in the absence of oxygen.
