How many molecules of carbon dioxide (CO2) would be produced by five turns of the citric acid cycle?

Biology
1 answer:
ser-zykov [4K]3 years ago
8 0

Answer:

The correct answer is E) 10

Explanation:

Glucose is partially oxidized during the glycolysis process into two pyruvate molecules. Then these pyruvate molecules get totally oxidized into CO2 during the citric acid cycle. This citric acid cycle occurs in the matrix of mitochondria.

During a single turn of the citric acid cycle, 2 molecules of carbon dioxide are released. Apart from two molecules of CO2, 3 molecules of NADH, 1 molecule of FADH2 and 1 molecule of ATP or GTP are also produced.

So if 2 molecules of CO2 are produced in one turn therefore in 5 turn 10 molecules of CO2 will be produced.

I NEED HELP WITH A QUICK BIOLOGY QUESTION!
Lelechka [254]
Hello there! 

The most plausible answer here, I believe, would be Polymerase. 
Polymerase is responsible for joining nucleotides to create new strands of DNA, or, replicating. Hope this helps and have a nice day.

Compare and contrast nuclear fusion and nuclear fission.
Mnenie [13.5K]

Answer:

With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.

Q. Which of the following are true concerning living things? Check all that apply. (2 pts)
adoni [48]

Answer:

Explanation:

Answer: 2 They are composed of molecules that contain carbon-carbon bonds.  

3. They undergo chemical reactions to use energy they acquire from the environment.  

Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms  have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.

They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.

They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.

A particular species of sea bird underwent a genetic mutation that resulted in big beaks. The larger size of beaks helped the bi
Alla [95]

Answer:

The correct answers would be natural selection and high genetic variation in the species.

Natural selection refers to the natural phenomenon by which organisms which are better adapted or have survival traits tend to survive and reproduce more in the environment.

It leads to an increase in the frequency of the trait in a population.

Genetic variation refers to the sum total of all the genetic characteristics present in a population. Higher genetic diversity higher are the chances of a population to survive.  

Similarly, different sizes of the beaks are the result of high genetic diversity out of which large size beak was favored by natural selection.  

Ultimately, the large beak size trait spreads through the population.
