After glycolysis occurs, the products may enter the Krebs cycle. Which major products result from these reactions?

2 answers:

4 0

The third option from top is the answer. The major products that result from the Krebs cycle are NADH, FADH and ATP in that order.

The Krebs cycle is the central metabolic pathway in all aerobic organisms. The cycle is a series of eight reactions that occur in the mitochondrion. These reactions take a two carbon molecule called acetate and completely oxidize it to carbon dioxide.

The Krebs cycle serves two main purposes namely:

1.To increase the cell's ATP producing potential by generating reduced electron carriers such as NADH and reduced ubiquinone.

2. To provide the cell with a variety of metabolic precursors.

By the time the eight reactions in Krebs cycle are over, one ATP, one FADH and four NADH molecules will have been produced

One way to reduce the shortage of food for a growing population would be

SpyIntel [72]

The most obvious way to reduce the shortage of food is to reduce population which seems like a long term effort however science has enables us to develop certain ways that could be used to reduce the shortage of food. We are familiar with the term genetically modified plants and animals.

This technique has enabled us to produce plants and animals of our choice at a faster rate than normal.

With the help of this we can put desirable traits in organisms.

Which is considered the first stage of the cell cycle?

Citrus2011 [14]

The phases go prophase, metaphase, anaphase, and telophase starting with interphase. But the first stage would be Interphase.

1. What is the total magnification of an object if the ocular lens magnification is 20x and the objective lens magnification is

V125BC [204]

1. Answer: 900x

A typical microscope has two lens: ocular lens which located near the eye, and objective lens which located near the object. The image will undergo magnification of both lens. The total magnification of the object would be the product of both lens multiplication, not the sum. The multiplication will be: 20x * 45x= 900x

total mag= ocular * object

total mag= 20x * 45x

total mag= 900x

2. Answer: 100x

The total magnification of the object would be the product of both lens multiplication. If the total magnification 1000x, that mean it was the product of ocular lens and objective lens. If ocular lens magnification is 10x, objective lens magnification would be:

total mag= ocular * object

1000x= 10x*object

object=1000x/ 10x=

object=100x

3. Answer: 0.2 mm

The area of the microscope that can be viewed by the eye should be the same. But since the magnification is different, the actual area that it represent will be different. Microscope with bigger magnification will have smaller diameter of the field of view(DFV). Remember that micrometer(μm) is 1/1000 of millimeter(mm). The DFV would be:500 μm/ ( 1000x/400x)= 200μm= 0.2 mm

4. Answer: 750μm

This question is similar to number 3 question. Remember that 1 millimeter(mm) equal to 1000 micrometer(μm) .

The DFV of a 10x objective lens is 3 mm. Then the DFV of 40x lens would be:

DFV2= DFV1/ (mag1/mag2)

DFV2= 3mm/ ( 40x/10x)= 0.75 mm= 750μm

5. Answer: 125μm x 37.5μm

The lens DFV of microscope from question 4 is 750μm, so the width and length of the area would be 750μm.

If 6 organisms could fit across the DFV if they were laid end-to-end, the length would be: 750μm/ 6 organism= 125μm

If 20 organism could fit is stacked side by-side, then the width would be: 750μm/ 20 organism= 37.5μm

6. Answer: 6mm

This question is similar to number 3 and number 4 question. Remember that 1 millimeter(mm) equal to 1000 micrometer(μm).

The DFV of a 100x objective lens is 1.5 mm. Then the DFV of 25x lens would be:

DFV2= DFV1/ (mag1/mag2)

DFV2= 1.5mm/ (100x/25x)= 6 mm

7.Using the 100x objective lens from question 6, you estimate 12 organisms could fit across the DFV if they were laid end-to-end and 30 could fit is stacked side-by-side. What is the length and width of this organism (in microns)?

Answer: 0.5mm x 0.2mm or 500μm x 200μm

The lens DFV of microscope from question 6 is 6 mm, so the width and length of the area would be 6 mm.

If 12 organisms could fit across the DFV if they were laid end-to-end, the length would be: 6mm/ 12 organism=0.5mm

If 30 organism could fit is stacked side by-side, then the width would be: 6mm/ 30 organism= 0.2mm
