the layer in the earth I did it before
n descriptive investigations, we still haven't formed any hypothesis yet so we seek information by asking question.
It's net repeatable because repeating the questions over and over again without any clue about what we want to seek is completely waste of time
A. During aerobic respiration, cells take in O2 (Oxygen is an input of cellular respiration) and release CO2, H2O and ATP.
Cellular respiration equation (THIS IS VERY USEFUL :) ):
C6H12O6 (Glucose) + O2 (Oxygen) = 6CO2 (Carbon dioxide) + 6H2O (water) + 36-38 ATP (energy)
NOTE: Inputs are the things going in, outputs are the things being produced.
WHY THE OTHER ANSWERS ARE WRONG:
B. Not B because it mentions the process of fermentation which is anaerobic.
C. Not C because insulin has nothing to do with cellular respiration in particular but rather blood glucose level homeostasis
D. Not D because although it is partially 'correct', the actual wording (inhaled /exhaled) is incorrect as H2O is produced not exhaled. ATP energy is also produced.
is there a picture near the question?
Answer: <u>Option 4; Oxygen gains electrons and hydrogen to form water.
</u>
Respiration is a process where glucose is used and energy is released stored in this molecule. Oxygen is used during respiration as well and it gains the electrons and hydrogen to form water. And, gain of electrons is an oxidation reaction. So answer is option 4.
Since, oxygen is consumed during respiration, option 1 is incorrect.
Loss of electrons is reduction, so option 2 is also incorrect.
Glucose is used in respiration, thus option 3 is incorrect.
