C₄ plants differ from C₃ and CAM plants in that C₄ plants _____. a. transfer fixed carbon dioxide to cells in which the Calvin c
lana [24]

Answer:

The correct answer is -transfer fixed carbon dioxide to cells in which the Calvin cycle occurs

Explanation:

In C4 plants the light reaction and Calvin cycle occurs in two different cell that are mesophyll cell and bundle sheath cells. First, the CO₂ is fixed into 4- carbon oxaloacetate by an enzyme PEP carboxylase.  

Then this oxaloacetate is converted into a simpler form called malate. Malate molecule then enters into bundle sheet cell and there it releases one molecule of CO₂. This CO₂ enters the Calvin cycle which results in the sugar formation with the help of enzyme rubisco.

Therefore by releasing of CO₂ molecule by malate in bundle sheet cells, it transfer fixed carbon for the Calvin cycle to occur.

If CPR is not performed, how many minutes will elapse before the brain becomes damaged from lack of oxygen?
attashe74 [19]
If CPR is not performed, C. 4 minutes will elapse before the brain becomes damaged from lack of oxygen.
One minute isn't enough time - you can even hold your breath for one minute without fainting. Some people can even do it for 2 minutes.
Ten minutes is too long - you would be long dead.
