Differenciate between intracellular enzymes and extracellular enzymes.

Answers

Answer 1

Answer: Intracellular digestion takes place in animals without a digestive tract, in which food items are brought into the cell for digestion. Extracellular digestion is a process in which animals feed by secreting enzymes through the cell membrane onto the food.

Transcription factors function to help move ribosomes along the mRNA. True or false?

Answers

Answer:

False

Explanation:

Transcription factors are proteins that bind to the DNAand regulate the transcription of genes to mRNA. They recognize specific sequences in the DNA and control the rate of gene transcription. Which genes will be expressed in a certain cell or tissue depends on what transcription factor is present in that cell or tissue.

What two components are often found as part of an enzyme?

Answers

The two components which are often found as part of an enzyme are Active site and protein. Proteins are referred to as macromolecules or macromolecules which consists of more or one of a chain of amino acid residue. They do perform an array of functions which are within organisms. For example, DNA replication, responding to stimuli, catalyzing the metabolic reaction. An active site is referred to as the region of an enzyme where substrate molecules bind and also they undergo a chemical reaction. They contain of residues which form temporary with the substrate and also catalytic site which catalyzes a reaction.

Answer:

Protein (the apoenzyme) and active site (cofactor) is the correct answer.

Explanation:

The two components are often found as part of an enzyme are

Protein (the apoenzyme)

proteins increase the rate of reaction that takes place within the living organism.

proteins consist of one or more chains of amino acids that make macromolecules.

They perform important functions within the organism such as proteins function is to catalyze the reactions that are necessary to our metabolism.

Active site (cofactor)

Active site:is the site where the enzyme binds with the substrate to initiates the reaction.

Identify the following description if the feaures is a transcription, translation, or neither. 1) Two DNA molecules result from one original molecule. 2) Amino acids are linked together at ribosomes. 3) RNA base sequences complementary to those in DNA are built. 4) Complementary tRNA bases match up to mRNA bases

Answers

1) Two DNA molecules result from one original molecule. - neither
2) Amino acids are linked together at ribosomes - translation
