Explain why fermentation wold take over and not the krebs cycle.how long would it last?

Biology

AleksandrR [38]3 years ago

Answer:

Fermentation replaces the Krebs cycle when there is inadequate oxygen and lasts for a much shorter duration, which depends on the individual.

Explanation:

The best way to describe this is when someone is running. While they are exerting their maximum effort, they breathe very heavily to make up for a lack of oxygen. The muscles they are using take up more oxygen than the lungs can obtain, so the cells switch over from the more efficient Krebs Cycle as a last-ditch effort to provide the energy that individual needs.

This is a very inefficient way of producing ATP because it only yields 2 ATP per glucose molecule, as opposed to roughly 26 ATP through the Krebs Cycle.

One common misconception here is that lactic acid buildup occurs during this process, and while that is partly true, the lactic acid would suffocate the cells and lead to death if lactic acid were to build up in the way people believe.

As for how long Fermentation can occur, it depends on the fitness of the individual, as the Fermentation process would likely only last for a few seconds for an out-of-shape individual and over an hour in a long-distance runner.

It also depends on whether or not the person has trained their muscle for endurance or short bursts of strength. A sprinter cannot use Fermentation for long but a marathoner may use Fermentation for the last hour of their run.

What is water’s role in the light reaction of photosynthesis?
notsponge [240]

The correct answer is - Its electrons are used to form NADPH.

On receiving light energy, electrons are expelled from the reaction center of photosystem II. The expelled electrons finally reduces oxidized NADH⁺ to NADH. The oxidized reaction center of photosystem II split water into protons, electrons and oxygen. The electrons released from water reduces oxidized reaction center of photosystem II. Thus, oxidized reaction center of photosystem II gets back its expelled electrons. Therefore, electrons from water forms NADH.

Which of the following statements is/are incorrect? a) The epidural space is located between the dura mater and the vertebral ca
dsp73

Answer:

C

Explanation:

The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.

A) The Dura mater

B) The arachnoid mater

C) The pia mater

The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.

The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.

The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.
