Answer:
Active Transport: Active transport pumps molecules through the cell membrane against the concentration gradient.
Passive transport, also known as passive diffusion, is a process by which an ion or molecule passes through a cell wall via a concentration gradient, or from an area of high concentration to an area of low concentration.
Explanation:
I just have a question, are you in seventh grade? I keep my binders from past years and I remember learning this, but don’t know if that’s the grade I learned it in, are you?
Two major steps are needed to obtain a protein from a gene. Transcription makes it possible to obtain a copy of the gene present on the chromosome, in the form of a messenger RNA (mRNA). Translation is the stage during which this mRNA is read by the ribosome to obtain a protein.
DNA replication is associated with photocopy because replication will give an identical copy of the cell DNA.
Transcription is associated with book printing because in transcription the genetic information will be transferred to another platform (RNA)
Nucleus in a Library since this is where the "book printing" occurs, and where the books (DNA) are
DNA is the book, where all the information are
RNA transcript is the photocopy
Translation is the cooking since it is the protein synthesis
Proteins/polypeptide is the cooking objective, so it is the prepared dish
RNA polymerase is the Xerox machine, it will copy the information in the DNA to RNA transcript
Ribosomes is the cooks, because this is where translation occurs
Activator protein are the bookmarks because it choose wich part of DNA it has to be transcript.
<h3><u>Answer;</u></h3>
- Catabolism is the process in which complex substances are broken down, yielding a net output of energy
- Metabolism is an integrated system in which many of the same reactions participate in degradative (catabolic) and biosynthetic (anabolic) pathways.
<h3><u>Explanation</u>;</h3>
- Metabolism is the chemical processes occurring within a living cell or organism that are necessary for the maintenance of life. In metabolism some substances are broken down to yield energy for vital processes while other substances, necessary for life, are synthesized.
- Catabolism is the metabolic breakdown of complex molecules into simpler ones, resulting in a release of energy. These reactions are exothermic.
- Anabolism involves the synthesis of polymeric biomolecules and complex lipids from monomers such as fatty acids and nucleotides. Anabolic reactions are endothermic.
