The enzyme catalyzes (speeds up) the rate at which the substrate is broken down.
Answer:
See the answer below
Explanation:
The central dogma gives a description of how genetic information travels in biological cells from DNAs to proteins. DNAs are first transcribed into messenger RNAs in a process known as transcription and the resulting mRNAs are used in the synthesis of proteins in a process known as translation.
In eukaryotic cells, transcription process happens within the confines of the nucleus because the genetic material in the form of DNAs are always located in the nucleus. Thereafter, the mRNAs generated from transcription are transported to the cytoplasm of the cell where they become translated into proteins.
Hence;
- <em>T</em><em>ranscription</em><em> happens in the </em><em>nucleus</em><em> of the cell.</em>
- <em>Translation </em><em>happens in the </em><em>cytoplasm</em><em> of the cell.</em>
Answer: False
In cellular respiration, <span>organic molecules are break down and it uses
an electron transport chain for the production of ATP through oxidative
phosphorylation. Here, the hydrogen ions are pumped into the mitochondrial
intermembrane space and they flow back through ATP synthase that produces most
of the ATP associated with cellular respiration.</span><span>

Answer:
Microvilli is very common in these cells. They increase the absorption area.
Explanation:
Epithelial cell surfaces show different structure shapes that allow the cells to adapt to and accomplish their functions. Most of these structures are related to the absorption surface and the need to move substances.
The development of microvilli is very common in epithelial cells. These are folds or finger-like projections emerging from the apical surface of the cell. <u>Their principal function is to absorb</u>. The microvilli of the intestinal epithelium are very uniform in size and distribution.
A virus is a microscopic parasite that infects cells in biological organisms, they reproduce only by invading and controlling other cells as they lack the cellular machinery for self reproduction. Additionally, viruses contain at least one unique protein synthesized by specific genes in the nucleic acid, the proteins forms a shell called capsid around the nuclei acid.
