For each glucose that enters glycolysis, _____ acetyl CoA enter the citric acid cycle. For each glucose that enters glycolysis,
klio [65]

Answer:

For each glucose that enters glycolysis,  <u>2 </u>acetyl CoA enter the citric acid cycle.

Explanation:

<u>SYNTHESIS OF 2Acetyl CoA -:</u>

The glucose is transformed into 2pyruvate (6 carbon molecules are converted into 2 -3 carbon molecules) during glycolysis. In both aerobic and anaerobic respiration, glycolysis occurs frequently. This process takes place in the cytoplasm (it does not require oxygen or mitochondria), but if both oxygen and mitochondria are present, two molecules of pyruvate join mitochondria and prepare for citric acid cycle.

Until entering this, the molecules go through a mechanism known as the linked (connects glycolysis with citric acid cycle) reaction, in which the pyruvate molecule is transformed into 2 acetyl CoA (meaning 3 carbon molecules are converted into 2 carbon molecules) and a carbon molecule is released in the form of 2CO_2 (waste product).

2NAD+ and NADH are synthesized in the linked reaction, implying that reducing power is produced. It means that electrons from pyruvate are released in the form of hydrogen, which 2NAD+ accepts and reduces to form 2 NADH.          

Glucose → 2pyruvate → 2Acetyl CoA

<u>Linked reaction is also known as oxidative -dicarboxylation.</u>

Hence,  2 Acetyl CoA is required to enter citric acid cycle.

State the significance of the peripheral nervous system
Serhud [2]

Answer:

              The human body  have two parts of nervous sytem the peripheral nervous system and the central nervous system

Explanation:

                        Peripheral nervous system contain all the nerves and ganglion that lies out side of the spinal cord and the brain.These two systems communicate with each other to make the body functional. The main function of the PNS is to connect the CNS to limbs and organs. Unlike the CNS the PNS is not protected by the vertebral column and skull.The peripheral nervous system is divided in to the somatic nervous system and the autonomic nervous system. The autonomic nervous control on the smooth muscles and glands.The connection between the CNS and organs keeps the body in sympathetic or parasympathetic  condition.

Suppose that a late succession plant that is surrounded by early succession plants grows at a rate of 0.5 cm per day. If the ear
inessss [21]

Answer:

negative, inhibition

Explanation:

The experiment in the illustration shows that early succession plants have a <u>negative </u>effect on the late succession plants, and the observation is most consistent with the <u>inhibition</u> model of succession.

<em>That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.</em>

There are 3 different models of succession. These include;

  1. Facilitation model in which colonists modify the environment to favor the growth of later successional species.
  2. Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.
  3. Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.
