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.
Answer:
When animals eat their food combine with oxygen, which produces energy for the animals to use for everyday activity and then gives off carbon. The carbon then combines with the oxygen to form carbon dioxide, which is then released back into the atmosphere as waste product when the animals breath.
Carbon Dioxide (CO2)
Hope this helps ;)

sorry if im wrong i tried
Explanation:
Answer:
First the proprioceptors found in the tissues will capture tissue damage and the presence of a continuity solution in the skin, then these receptors will activate the afferent pathway, which is the pathway of pain, which is sensory.
This stimulus that ascends to the central nervous system activates the "flight" mechanism in the face of pain (it is also known as the withdrawal mechanism).
It is in this way that a stimulation is sent to the alpha motor neuron in the form of an action potential as an efferent pathway to the skeletal muscles of the foot and the damaged leg, so that an automatic and involuntary muscle contraction is generated in a matter of millisemas of second after the damage, so the foot is removed from the damage area.
Explanation:
The withdrawal mechanism is a reflex that the human acquires before pain, that is why it is the muscular contraction is automatic and fast once the pain occurs.
So as a summary: 1 - the proprioceptors of the damaged tissue are activated 2- the signal of tissue damage rises as afferent to the CNS 3- the CNS responds by activating a signal that will be sent by interneuronal connections to the alpha motor neuron 4- the signal arrives as potential of action to the alpha motor neuron that innervates the muscles of the surrounding area to which it is damaged 5 - the muscles contract, generating the withdrawal of the limb.
Answer:
The air is thinner higher in the atmosphere. making it hard to breath and not having enough air.
