1. False
2. Sugar (glucose)
I took this test, and these were right ;)
Explanation:
the carbon cycle is the biogechemical cycle by which carbon is exchanged between the biosphere, pedosphere, hydrosphere and the Earth's atmosphere
<h2><u>Answer</u> : </h2>
Proteins are basic nutrients comprising biomolecules, which are made up of long chains of Amino acids.
They have various functions in our body :
- they make up our hair, nails, bones etc
- they helps in recovery of damaged tissues (therefore known as body - building food)
- the structure and functions of protein depends on base sequence of nucleotides in the DNA coding for that specific protein.

Answer:
1 H is consumed in exchanging the synthesized ATP in mitochondria with ADP in cytosol by adenine nucleotide translocator (ANT).
Explanation:
The electrons from NADH and FADH2 are transported in electron transport chain through various complexes that act as electron transporter, to oxygen. In this process, the pumping of protons from mitochondrial matrix to intermembrane space causes a concentration gradient and hydrogen ions diffuses out of matrix space through ATP synthase causing the production of ATP.
3 H are enough to pass through ATP synthase for the phosphorylation of ADP to produce ATP. 1 H or 25% of energy yielded from electron transfer is required to exchange the matrix ATP with the ADP in intermembrane space by adenine nucleotide translocator (ANT). This process provides continuous supply of ADP to mitochodaria and ATP which is exported to cytosol is utilized by cell to perform various functions. There will be no ATP production in mitochondria without ADP. So 4 H are required for 1 ATP production.
1 H for importing ADP to mtichodaria + 3 H for phosphorylation of ADP to ATP
Symbiotic Relationship.
Hope this helps.
