Answer:
Substrate-level phosphorylation, which is a process of forming ATP by the physical addition of a phosphate group to ADP can take place in the cytoplasm during glycolysis or inside the mitochondrial matrix during the Krebs cycle.
Explanation:
Substrate-level phosphorylation is a metabolic reaction that results in the formation of ATP or GTP by the direct transfer of a phosphoryl (PO3) group to ADP or GDP from another phosphorylated compound.
Answer:
D. Molecules called pumps function to control active transport.
Explanation:
Active transport is one of the two types of transport (the other being passive transport). It is the type of transport in which substances move against their concentration gradient i.e. from a lower concentration to a higher concentration. Hence, due to this, energy input in form of ATP is required by the cell.
However, the process of active transport makes use of certain molecules called PUMPS to control it. The pumps moves ions/molecules against their concentration gradient. An example is the sodium-pottasium pump which moves sodium ions from a region of low conc. to a region of high conc.
Cohesion causes water molecules to stick to each other. Cohesion is the attraction of like molecules
NITROGEN FIXING BACTERIA processes nitrogen in the atmosphere and make it available to other living forms in a usable form. Nitrogen fixing bacteria are micro organisms which are capable of transforming atmospheric nitrogen into fixed nitrogen. An example of a nitrogen fixing bacteria are bacteria in the genera azotobacter.
Answer:
Myelodysplastic (Ans. A)
Explanation:
Acute myeloblastic leukemia (AML): Is also called malignant blood cell cancer which can affect both adults & children. It is a fast-growing malignant disease where too many immature myeloblasts (WBS) are found in the RBC & bone marrow. Acute myeloblastic leukemia starts while chronic leukemia present from a long time & grow gradually. Symptoms of acute myeloblastic leukemia are:
High fever, a large no. of infections over a short period, pain in the joints, sweating a lot, etc.
Myelodysplastic syndrome: It is a group of disorder caused by blood cells (which is immature & don't work properly). Instead of developing properly the blood cells die in the bone marrow. After sometimes there are more immature cells than healthy ones, causing the problems infection caused by leukopenia, etc.
