The CNS is vulnerable. There are several systems and structures in place which protect these vital tissues. How is the brain and

V125BC [204]

Answer:

1) Skull and Vertebral column

2) Meninges

3) Cerebrospinal fluid.

Explanation:

Central Nervous system:

CNS is the abbreviation of Central Nervous system. CNS controls the whole body functions so it is the most important component of the body. CNS consist of two parts 1) Brain and 2) Spinal cord

Both of these organs are very important and hence need to be protected. Nature provided these organs with certain protective mechanisms these includes

1) Skull and Vertebral column:

Skull is present around brain and vertebral column is present around spinal cord. These structure provides mechanical support to soft parts of CNS.

2) Meninges:

These are the membranes that provide antiseptic environment to the brain and hence protect it from microbes and other harmful substances.

3) Cerebrospinal fluid:

This fluid is present inside meninges which nourishes the brain and protect it from mechanical stresses.

Cellular respiration map

nexus9112 [7]

Explanation:

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Further Explanation:

In all eukaryotic cells, mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced.

Oxidative phosphorylation follows; this is a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP. At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water...

Glycolysis: occurs in the cytoplasm. 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules. (2 ATP are utilized for a net ATP of 2)

The Citric acid or Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate, 2 ATP oxygen molecules, 8 NADH and 2 FADH2.
The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2, renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

How does h2o and co2 get transported into the chloroplast?

mixas84 [53]

Answer:

<h2>The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. ... In these reactions, the energy from ATP and NADPH is used to fix carbon dioxide (CO2).</h2>
