Answer:
The correct answer is B high levels of lactose and high levels of cyclic AMP.
Explanation:
Lac operon contain 3 regulatory genes and 3 structural genes.In presence of lactose the repressor molecule that is encoded by Lac I gene cannot bound to the operator region.
Bacause the lactose interact with the repressor and change its conformation so that it cannot repress the expression of the structural genes of lac operon.
On the other hand cyclic AMP is a positive regulator of lac operon .The interaction of cyclic AMP with the promoter region of lac operon stimulates the binding of RNA polymerase in the promoter region to boost the expression of structural genes of lac operon such as Lac Z,Lac Y and Lac A.
<u>Answer</u>: d. it will release chemical messengers.
The action potential, which is an electric pulse, will travel down the axon untill it reaches the synapses. At the synapses, neurotransmitters (chemical messengers) will be released by the neuron.
Answer:
The correct answer is given below:
Explanation:
Depending upon the availability of oxygen, pyruvic acid follows, a variety of metabolic pathways.
In the absence of oxygen or under anaerobic conditions, the pyruvic acid further metabolised into one of three pathways: lactic acid fermentation, alcohol fermentation and cellular anaerobic respiration. During fermentation or anaerobic respiration 2 ATP is produced.
In the presence of oxygen or under aerobic conditions, the pyruvic acid completely oxidised to carbon dioxide, water and 38 ATP.
