Explanation:

When the high energy electrons move from the reactive center, they are conveyed from one chain protein to another as the energy in the electrons is harnessed to pump H+ ions from the stroma into the lamellae. The electron will ultimately reduce NADP+ to NADPH and the electrons in the reactive center will be replaced by high energy electrons from the splitting of a water molecule in photolysis. The energy of the sun is used to split the water molecule. The high energy electrons then undergo the same cycle as the previous electrons and the cycle continues.

Eventually a proton-motive force is created across the lamellae membrane. This potential energy of the high H+ ion gradient is used by ATP synthase enzyme to phosphorylate ADPs to ATPs.

How does PAMPs activate infectious Inflammation​
Juliette [100K]

Answer:

Activation of infectious inflammation:

PAMPs are derived from microorganisms and thus drive inflammation in response to infections. After identifying microorganisms infections PAMPs by PRRs, activate cytoplasmic complexes called inflammasomes.

After activation of inflammasomes, these inflammasomes activate the protease caspase-1, which then cleaves or breaks various pro-inflammatory cytokines, resulting in maturation and cellular release that cause inflammatory reactions.

Aleksandr-060686 [28]

Answer:

"I will take three nitroglycerin tablets 5 minutes apart, and if I do not have any relief I will seek emergency care immediately."

Explanation:

You experimentally change the DNA sequence directly upstream of a start codon of an operon in E coli to investigate the function
Phoenix [80]

Answer:

Mutation occurred in ribosome binding site that serves as binding site for 30S ribosomal subunit of <em>E. coli</em> and allows the process of protein synthesis to begin.

Explanation:

The initiation of protein synthesis in bacteria requires binding of the ribosome to the ribosome binding site. The ribosome binding site in bacteria consists of the initiation codon "AUG" and the preceding Shine-Dalgarno sequence. The AUG initiation codon and Shine Delgrano sequence are around 10 bases apart.

The sequence is polypurine hexamer and is represented by 5' ...AGGAGG...3'. Shine-Delgrano sequence is complementary to the conserved sequence present at the 3' end of 16SrRNA of the 30S subunit of the bacterial ribosome. Binding of Shine Delgrano sequence of ribosome binding site and the complementary sequence of the 30S ribosomal subunit marks the first step in the initiation of protein synthesis.

Any mutation in the ribosome binding site would not allow the process of protein synthesis to start or would reduce the rate of the initiation of protein synthesis.
