Answer:

In muscle tissue

Explanation:

People who exercise daily, their metabolism rate is very high and the consume sugar, proteins and fat as a substrate for providing ATP molecules. The ATP molecules are then utilized by the body to perform physical work.

The physically active people when they require fat in their diets, the fats first will be stored in the muscle tissue as the cells there will use fat as a substrate for providing a large amount of energy that is 1 g of fat will provide 9 kcal.

Thus, muscle tissue is the correct answer.

What does the operon model attempt to explain?
sergiy2304 [10]

Answer:

a. the coordinated control of gene expression in bacteria

Explanation:

An operon in bacteria is a collection/cluster of genes that are under the control of a single promoter. It includes 3 components: a promoter, the genes and an operator. The operator is where a repressor binds, and the promoter is where transcription begins.

Operons allow organisms to control the expression of multiple genes in response to environmental cues

Which of the following is an example of a non-falsifiable hypothesis?
OLEGan [10]

Answer: There is a teacup orbiting the Milky Way galaxy.

Explanation: Hello!

To find the correct answer, you need to find a hypothesis that cannot be proven wrong. All but one can indeed be proven wrong. The correct answer is there is a teacup orbiting the Milky Way galaxy because there is no way anyone can tell if there is a teacup orbiting the Milky Way galaxy or not. We know that it can be proven wrong because there is no life on Mars, the human species started in Africa and that humans cannot live without a certain amino acid. The only thing that really can’t be proven wrong is the one about a teacup.

The lac operon can be regulated by two distinct methods. Which of the following statements are correct?The lac operon can be act
Ad libitum [116K]

Answer:

  • The lac operon can be activated by the binding of allolactose to the repressor protein, releasing it from DNA and thereby allowing for transcription to occur.
  • In response to low glucose levels, cAMP is upregulated; the binding of cAMP to the cAMP receptor protein triggers the activation of the operon.

Explanation:

Lactose operon or lac operon  (includes lacZ, lacY and lacA genes) is found in some bacteria and the products of its genes are involved in lactose metabolism. So, this operon is active (genes are transcribed) when lactose is present and glucose is absent (or at low level). The operon is regulated by the lac repressor which acts as a lactose sensor and catabolite activator protein (CAP) which acts as a glucose sensor.

When there is lactose (in the form of allolactose) lac repressor detects it and stops being repressor. This enables transcription.

CAP detects glucose (via cAMP) and activates transcription when glucose levels are low.
