Answer:
tumor suppressor gene
Explanation:
A tumor suppressor gene is capable of modulating cellular processes during cell division and/or replication, thereby avoiding uncontrolled cell proliferation and tumor development. For example, the p53 gene is a tumor suppressor gene that encodes a protein (p53) which is well known to regulate critical cellular processes such as, for example, cell cycle arrest and programmed cell death (apoptosis). Moreover, breast cancer genes BRCA1 and BRCA2 are tumor suppressor genes that regulate the repair of damaged DNA through the Homologous recombination (HR) pathway. In consequence, mutations in BRCA1 and BRCA2 genes can increase the risk of developing breast cancer.

Explanation:
Transgenic organisms can be described as organisms which have a foreign gene inserted into their genome. Transgenic organisms are of huge economic importance and are emerging to provide benefit for humans and the Earth.
The transgenic organisms are being used as a replacement for fuel which will benefit the humans and the Earth.
Transgenic organisms have evolved and made strong roots in the field if medicine in today's world.
Transgenic plants are being used to produce crops which are resistant to pests and hence are of huge economical importance.
Answer:
Aerobic respiration is the process or set of cycles that producing cellular energy with the help of oxygen. In this process cells, breakdown glucose in the multi-step process in which the very first step is glycolysis, the second is the Krebs's cycle and the third is the electron transport system in the mitochondria.
<u>Glycolysis</u>: It is the first step of cellular respiration that is enzyme based metabolic reaction that converts glucose into pyruvate and releases energy in the form of ATP and NADH. The net gain of the pathway is two ATP and two NADH.
Pyruvate oxidative link is an intermediate reaction between glycolysis and Krebs cycle that converts pyruvate to acetyl CoA.
<u>Krebs cycle:</u> It is a pathway involves chemical reactions release stored energy through the oxidation of acetyl CoA derived from pyruvate into adenosine triphosphate and carbon dioxide.
<u>Electron transport system:</u> all previous steps reduce the electron carriers to NADH + H+ and FADH2. Then these donate protons and electrons to the electron carrier proteins of the ETS system. In the end, the electron accepted by oxygen.
