Answer:

It would have disastrous consequences on the viability of the individual

Explanation:

The genome can be defined as the genetic material of an organism, which is composed of DNA molecules named chromosomes whose building blocks are four different nucleotides: Adenine, Thymine, Cysotcine and Guanine. The order of these nucleotides specifies the information contained in the chromosomes and, ultimately, in the genome. The genes, which are recognized to be the basic units of inheritance, are genetic sequences composed of ordered nucleotides along the chromosomes. During transcription, a gene encodes different RNA codons (for example, start and stop codons) which are specified by the order of the nucleotide sequence. Finally, the order of the RNA codons will be critical to specify the polypeptide chain during the translation from RNA to protein.

Insect hormones and their receptors ________. A. act independently of each other B. are a focus in pest control research C. util
Leokris [45]

Insect hormones and their receptors are a focus in pest control and research. Hence, Option B is correct.

Some of the insect hormones such as ecdysone (molting hormone), JH (juvenile hormone) and their analogs can be used for biological  control of pests.

Option A: Hormone receptors are proteins that bind hormones and form hormone receptor complex to maintain cellular activities.

So Option A is incorrect.

Option B: Some of the peptide hormones used in pest control and research. So Option B is correct.

Option C: Peptide hormones interact with only cell surface whereas aminoacid derivatives and thyroid hormones directly interact with nucleus. so Option C is incorrect.

option D is incorrect.

Zigmanuir [339]

Answer:

The correct answer is : C .It will decrease ATP production because fewer protons will be able flow down through ATP synthase.

Explanation:

  • Oxidative Phosphorylation is a process which involves two steps:  
  1. Transport of electrons from the reduced compounds like NADH (Nicotinamide adenine dinucleotide hydrogen) and FADH₂ (Flavin adenine dinucleotide dihydrogen) through the electron transport complexes, located in the inner mitochondrial membrane, to oxygen for the generation of water molecules.
  2. Synthesis of ATP or adenosine triphosphate from ADP or adenosine diphosphate and inorganic phosphate by an enzyme called ATP synthase which is located in the inner mitochondrial membrane. This enzyme harnesses energy by carrying protons from the inter-membrane space into the mitochondrial matrix and in the process produces ATP.
  • Oxidative phosphorylation takes place in the mitochondria, especially involving the inter membrane space, inner membrane and mitochondrial matrix
  • During the transport of electrons through the protein complexes (I, II, III, IV) of the electron transport chain a proton gradient is generated across the inner mitochondrial membrane.
  • The proton gradient is such that the concentration of protons is more in the inter-membrane space and less in the matrix of the mitochondria.
  • This proton gradient provides the energy to the ATP synthase for the synthesis of ATP.
  • Dinitrophenol is responsible for making the inner mitochondrial membrane permeable to protons. As a result protons can directly diffuse through the inner mitochondrial membrane from the inter-membrane space into the mitochondrial matrix equalising the concentration of protons across the inner mitochondrial membrane. This causes distortion in the proton gradient.  Hence, protons are no longer available for the ATP synthase to operate and synthesise ATP.
