The part of the carbon cycle that takes in oxygen and a carbon-containing sugar and releases carbon dioxide.

I belive it would be respiration

Because respiration occurs in animals and plants after the intake of food or oxygen. A series of reaction occur with oxygen to convert glucose(sugar) into carbon dioxide,water, and energy.

Hope this helps some :)

What is the main determining factor of the boundary between the layers
makvit [3.9K]

Explanation:

The atmospheric boundary layer is defined as the lowest part of the troposphere that is directly influenced by the presence of the earth's surface, and responds to surface forcing within a timescale of about an hour or less.

What is an example of creatine phosphate?
slega [8]

In the process of regeneration of ATP, creatine phosphate transfers a high-energy phosphate to ADP. The products of this reaction are ATP and creatine. Creatine phosphate can be obtained from two sources: ingestion of meat and internal production by the liver and kidneys.

How does kinetic energy affect a popsicle freezing as it changes its state of matter:
VMariaS [17]

As ice melts into water, kinetic energy is being added to the particles. This causes them to be 'excited' and they break the bonds that hold them together as a solid, resulting in a change of state: solid -liquid.

<h2>Lac operon </h2>

Explanation:

Lac operon present in prokaryotic chromosomes whose product involves in transportation and catabolism of lactose

  • Lac operon consists of three structural genes called Lac Z,Lac Y and Lac A and a regulatory element(promoter and operator)
  • Lac I gene is present outside the Lac operon,act as regulatory gene and control the expression of Lac operon genes
  • Lac Z codes for β galactosidase which converts lactose into allolactose
  • Lac Y codes for Lac permease which act as a membrane transporter and transport lactose into the cells
  • Lac A codes for transacetylase which neutralize the toxic effects of lactose

Lac operon in absence of lactose

  • In absence of lactose Lac operon exists in switch off state
  • Lac I gene produces Lac repressor which binds to operator region and prevent binding of RNA Polymerase thus blocks transcription

Lac operon in presence of lactose

  • In presence of lactose Lac operon exists in switch on state
  • In presence of lactose few molecules of Lac operon enzyme catalyse conversion of lactose to allolactose
  • Allolactose act as an inducer,binds to the Lac repressor and induce conformational changes causing dissociation of Lac repressor from operator
  • In absence of Lac repressor RNA Polymerase binds to the promoter and starts transcription of genes which catabolize lactose

Lac promoter is a weak promoter and direct transcription of Lac operon genes in very low level in presence of lactose

  • For higher level expression of Lac operon genes,operon system require conversion of weak promoter to strong promoter which is always mediated by catabolite protein-cAMP complex(CAP-cAMP complex)
  • CAP cAMP complex binds to the upstream of promoter called CAP binding site and stimulate expression of Lac operon genes by facilitating binding of RNA Polymerase
  • Catabolite activator protein(CAP) or cAMP receptor protein(CRP) activate when cAMP binds
  • cAMP is a secondary messenger synthesized from ATP and act as co-activator of CRP
  • With respect to CAP cAMP complex Lac operon system is positively controlled
  • In prokaryotic cell cAMP is very low when glucose concentration is relatively high and vice versa
  • At high concentration of glucose the growth rate is maximum and lactose catabolism is repressed called catabolite repression
