Antibiotics, antimicrobial resistance and the control of disease - Essay
kondaur [170]

<u>Antibiotics are used to kill bacteria:</u>

Antibiotic is a naturally produced substance that is used to kill bacteria. The first antibiotic was penicillin produced from fungus. The word antibiotic means against life which means it is against the life of pathogenic bacteria.

In the case of the living organism that is treated antibiotic is ‘pro life’. Antimicrobials are used to kill pathogenic microbes like fungus, bacteria, virus etc. Sometimes the microbes become resistant to the antimicrobials and they are said to develop is antimicrobial resistance.

When pathogens develop antimicrobial resistance newer drugs have to be developed in place of the earlier ones to treat the disease.

The energy required to run the Calvin cycle reactions of photosynthesis comes from which two substances produced during the ligh
Lelu [443]

Answer:

a. ATP and NADPH

Explanation:

Light-dependent reactions of photosynthesis include splitting of water in the presence of sunlight and release of electrons. The electrons move from the reaction center of the PS-II via electron carriers to the PS-I. From the reaction center of PS-I, the electrons finally reach NADP reductase and reduce NADP into NADPH.

During this electron transfer via electron carriers, a proton concentration gradient is generated across the thylakoid membrane. The energy of this gradient is used to drive ATP synthesis. ATP and NADPH formed during the light-dependent phase of photosynthesis are then used during the reactions of the Calvin cycle.
