Comparison of Photosynthesis and Cellular Respiration

Zigmanuir [339]

Explanation:

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

These end products, namely O2 and glucose are then used in respiration...

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

The CO2 and H2O produced as waste in respiration can then be incorporated at the beginning of photosynthesis. Thus the reactions are cyclic- they feed into each other.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

Occuring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

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.

Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycoysis). The electron transport chain, in which oxygen functions as the terminal electron acceptor occurs in both plants and animals.

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.
The 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.

E, F, G, or H

Though most of these are correct, I personally think that 'g' is the best answer.

classify the following characteristics and examples depending on what model of speciation is described.

kvasek [131]

The classification of the characteristics and examples based on the model of speciation that is being described are as follows:

<u>Allopatric Speciation:</u> speciation that is based on geographic isolation.
<u>Sympatric Speciation:</u> organisms are reproductively isolated by postzygotic mechanisms and evolve into different species.
<u>Allopatric Speciation:</u> organisms in different locations are subject to different selective pressures and evolve into different species.
<u>Sympatric Speciation:</u> speciation that does not require geographic isolation.
<u>Sympatric Speciation:</u> bread wheat evolved from two species of wheat with different chromosome numbers.

<h3>What is speciation?</h3>

Speciation can be defined as an ecological and biological process through which new species of a living organism are formed, especially due to isolation of a part.

<h3>The types of speciation.</h3>

In Science, there are five (5) major types of speciation and these include the following:

Allopatric Speciation
Peripatric Speciation
Parapatric Speciation
Sympatric Speciation.
Artificial Speciation.

What do you think the up and down arrows you carved into the spinal cord are meant to represent?

andreev551 [17]

The up and down arrows you carved into the spinal cord are meant to represent the movement of different nerve signals. These signals, which are slso called action potential, are coordinated movements of sodium and potassium ions that are psocessed across the nerve cell membranes

WILL MARK BRAINLIEST. Can someone help me wit des three questions?

VARVARA [1.3K]

Answer:

1. every organism on the food chain will be affected. the ones below it will have a higher population, and the ones above it will have a lower population.

2. biodiversity is the idea, that all life is different, and environments thrive with it.

3. biodiversity is important in an ecosystem because if you take out biodiversity, you essentially take out all the animals in the given ecosystem.

Explanation:

1. when you remove lets say a spider from a food chain, the bugs that it would've eaten will start growing in population from not being eaten by the spiders. the birds that wouldve eaten the spiders, will decrease from the lack of that food source.

2. is self explanatory

3. if you only had one type of bird in one ecosystem, and that was the only animal in that ecosystem, the birds would all die, because they wouldn't have anything to eat, and nothing would eat it, so they might resort to cannibalism, or, as earlier stated, they would die off, from lack of food. the ecosystem would not be sustainable.
