Answer:
B. Decrease
Explanation:
Positive feedback is an increase while negative feedback is a decrease.
Intermembrane space is the space between outer and inner membrane, of a mitochondria/ chloroplast. It is the site of oxidative phosphorylation process. H+ ions are transported from the cellular matrix to the intermembrane space, and this ultimately leads to generation of a proton graident and generation of energy. An increase in the intermembrane space may lead to decresae in the space of inner membrane and therefore, less space for electron transport chain and ATP synthase, which reside in the inner membrane. This ultimately leads to less energy production.
Answer:
Answer and Explanation: The channels and pumps that traverse the cell membrane are made out of proteins. Proteins can fold into a structure that allows specific materials to pass through them.
PROTO-ONCOGENES are corresponding normal cellular genes to an oncogene that is responsible for normal cell growth and division.
An oncogene refers to a gene that is capable of causing cancer due to damage to the DNA molecule either by virus or other DNA damaging agents. A proto oncogene is the normal version of the gene while an oncogene is the abnormal version of the concerned gene.
Mitosis in an eukaryotic cell cycle occurs after the G2 phase (option b). This is the final stage of interphase and during this time, the cell continues to grow as well as create new proteins. Successful completion of this phase results in the commencement of Mitosis.
