Answer:
Leukocytes are also called white blood cells. These cells have a nucleus, unlike red blood cells that lack a nucleus. Also unlike red blood cells, white blood cells do not contain hemoglobin, which means they're not involved in the transport of oxygen.
Answer: :
safranin counterstain
Explanation:
safranin counterstain is applied which stains all cells, allowing the identification of Gram-negative bacteria as well.
Answer:
Products of the pentose phosphate pathway contribute to reductive biosynthesis reactions
Pentose phosphate pathway activity is high in rapidly diving cells.
Glucose-6-Phospjate is common to glycolysis and the pentose phosphate pathway
Explanation:
Glycolysis is the major catabolic fate of glucose 6-phosphate. However, oxidation of glucose 6-phosphate to pentose phosphates occurs by the pentose phosphate pathway. Therefore, glucose 6-phosphate is common to glycolysis and pentose phosphate pathway.
Pentose phosphate pathway uses NADP+ as an electron acceptor, yielding NADPH. Rapidly dividing cells, such as the cells of bone marrow and skin use the pentoses as one of the precursors for the synthesis of RNA, DNA, and coenzymes like NADH, FADH2, and coenzyme A.
The NADPH formed during pentose phosphate pathway is needed for reductive biosynthesis by many tissues. For instance, liver and adipose tissues carry out the extensive synthesis of fatty acid and require NADPH. Likewise, the tissues involved in the active synthesis of cholesterol and steroid hormones (for example, adrenal gland and gonads) also require the NADPH which in turn is provided by the pathway.
We have two lungs, one left and one right.
Cacti and other succulents can adapt to dry climates. They are able to store water in their leaves, while others store water in the roots or trunks. The waxy cuticle helps prevent water loss.
