Answer:
A Cellular Respiration
Explanation:
This is because Photosynthesis takes CO2 and pushes our Oxygen, while the inverse is true for cellular respiration.
If an amino acid sequence is formed incorrectly (i.e. DNA point mutations or frameshift mutations) then the enzyme can either be dysfunctional or non-functional; both of which lead to the end point of enzyme deficiency and overt disease. For example, the mutation of the enzyme glucose-6-phosphate dehydrogenase or G6PD decreases the production of antioxidants which can lead to increased hemolysis of red blood cells causing the clinical manifestation of jaundice (since the end point of metabolism of hemoglobin is bilirubin).
Answer:
The statement is true.
Explanation:
The soluble nutrients from digestion (amino acids, sugars and soluble vitamins) travel from the intestine to the liver through the portal vein. The transport of lipids, cholesterol and fat-soluble vitamins is much more complex, since they are not soluble, they cannot be sent to the portal vein because there they would quickly produce fat deposits, and must be sent through the lymphatic system. Among the functions of the lymphatic system, two should be highlighted: its central role in the immune system, and its role in the transport of lipids and cholesterol from the diet. Lymphatic ducts from the intestine converge into the thoracic duct that joins the bloodstream near the entrance to the superior vena cava, where the lymph content passes into the systemic blood circulation.
Answer:
DNA do not normally cross the nuclear membrane.
Explanation:
DNA (Deoxyribonucleic acid) is present in the nucleus which contains the genetic information of an organism. Nucleus is necessary for whole the process of cell division and initiation. During cell division DNA plays a most important role carrying of genetic information of old cell to the newly synthesized cells, which only occurs during cell division.
All processes like replication and transcription needs enzymes which are normally found in the nucleus. So, for the protection of DNA keeping DNA within the nucleus and do not cross the nuclear membrane. If DNA is floating in the cytoplasm than DNA can not be transcribed its information into RNA and this process is known as transcription process (DNA into RNA).
