c. phospho anhydride bond hydrolysis

d. enzyme-mediated reactions

e. none is correct

some anoxygenic photosynthetic bacteria are able to use as an electron source.

a. light
b. co2
c. h2s
d. h2o
e. nitrate
only cause diseases under certain circumstances, e. g. in immune compromised hosts

ATP donates energy through C phospho anhydride bond hydrolysis.

Explanation:

ATP or adenosine triphosphate is an energy rich compound which contain 3 phosphate moiety that are linked by 2 high energy phospho anhydride bonds.

   The hydrolysis of phosphoanhydride bonds releases high amount of free energy which is used by cellular system of our body to exhibit various cellular,biological and physiological functions.

 Some anoxygenic photosynthetic bacteria are able to use H2S or hydrogen sulfide as an electron donor.

Opportunistic pathogens only cause infection under certain circumstances eg in immune compromised hosts.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
