<span>The correct answer is true. catabolic and anabolic reactions do in fact involve electron trasnsfer using reduction-oxidation reactions. For example, ATP donates one of it's phosphate groups to a coupled reaction thus forming ADP in a reduction reaction. It can then gain that phosphate group back utilizing an oxidation reaction.</span>
Answer:Fungi release digestive enzymes into their food and digest it externally.
Explanation:
They absorb the food molecules that result from the external digestion.

Answer: The lac operon is an inducible operon that is activated in the presence of lactose.
An operon is a unit of genes which are controlled by the single promoter and operator sequence. It consists of a regulatory gene, promoter, operator, and structural genes.
Lac (lactose) operon consists of three structural genes namely lacZ, lacY, and lacA. These genes are transcribed and translated to produce specific enzymes used for lactose metabolism.
It is called as inducible operon because lactose acts like an inducer as its presence induces the transcription process. The lactose is first converted into allolactose which then binds to repressor (synthesized by regulatory gene). In this way, it makes the repressor inactive and therefore allows the transcription of structural genes.
