Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
True or False:Both photosynthesis and cellular respiration involve an electron transport chain that makes ATP.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Both respiration and photosynthesis involve electron transfer across a series of electron carriers embedded in the inner mitochondrial membrane and the thylakoid membranes respectively. Cytochromes are responsible for ATP production through electron transport and are iron-containing proteins.

Detailed explanation-2: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.

Detailed explanation-3: -Both are processes within the cell which make chemical energy available for life. Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life.

Detailed explanation-4: -Which is true for both photosynthesis and cellular respiration? They require oxygen as a reactant.

Detailed explanation-5: -Explanation: In both cellular respiration and photosynthesis, chemiosmosis occurs. Chemiosmosis is the process in which the creation of a proton gradient leads to the transport of proton down its concentration gradient to produce ATP. This occurs in the electron transport chain in both mitochondrias and chloroplast.
