In glycolysis of cellular respiration, the pyruvate amounts to c^3h^4o^3. The amount for carbon and oxygen make sense as there a

re two pyruvates and together they amount to 6 carbons and 6 oxygens (the amount glucose has), but the amount of hydrogens don't add up. There are 8 in total (from both pyruvates) and 2 going to NADPH, but that amounts to 10 hydrogens, not 12. Are the other two hydrogens used during glycolysis elsewhere? Are they released in a different form? Am I missing something?

Elena L [17]

Answer:

The DNA is more closer to bacteria.

Explanation:

Mitochondria and chloroplast are considered as semi-autonomous organelle because they contain their own genetic material. The mitochondria and chloroplast evolution can be explained by the endosymbiont theory.

The DNA of mitochondria and chloroplast are more closely related to bacterial chromosome rather than eukaryotic chromosome.  Both the organelle and bacterial DNA are double stranded and  their translation can be inhibited by the chloramphenicol. Some of their replicating enzymes also show similar characteristics.

Thus, the DNA is more closer to bacteria.

Why do we have so much dna?
jasenka [17]

Answer:

Of the trillions of cells that compose our body, from neurons that relay signals throughout the brain to immune cells that help defend our bodies from constant external assault, almost every one contains the same 3 billion DNA base pairs that make up the human genome – the entirety of our genetic material. It is remarkable that each of the over 200 cell types in the body interprets this identical information very differently in order to perform the functions necessary to keep us alive. This demonstrates that we need to look beyond the sequence of DNA itself in order to understand how an organism and its cells function.

Hello,

Please find below a short summary on the subject you have been assigned. This will help you in completing your project and also give you an overview on the current research on this subject.

Food additives are chemical substances added to food in order to either maintain or improve its physical characteristics such as taste, texture, appearance and even freshness.

The long term effects that these substances have on the human body are still largely unstudied. According to the hypothesis called "chemical obesogen", these synthetic compounds are contributing factors to the global obesity epidemic.

Although evidence-based scientific research is still lacking, the support for this hypothesis is growing as many of these additives have been found to disturb the body's endocrine functions.

Furthermore, artificial preservatives used today may increase the risk of inflammatory bowel disease. This has been shown by a study on mice in which the food additives known as emulsifiers (carboxymethylcellulose and polysorbate-80) have been shown to affect the animal's health.

Due to these chemicals, the mice not only became obese but also developed metabolic problems such as glucose intolerance.  It seems that these chemicals affect the gut bacteria population in a negative way, as mice lacking gut bacteria did not become ill.

The mice study was followed by another study in which the human simulated through a series of flasks. Under the influence of the emulsifiers arboxymethylcellulose (E566 on EU labels) and polysorbate-80 (E433), the levels of bacterial protein called flagellin increased. This protein is known to cause inflammation at high concentrations. The next step in the study will be the first human trials.

Due to the long road our food takes from the farm to our table more extensive research is required. There are thousands of compounds that change the biochemical properties of the plants and animals that constitute our diet. The effects of the degradation and accumulation of these compounds are still unknown and thus many more studies and approaches are required in order to insure healthy food and stop the current obesity epidemic. Everything that is added to our food should be carefully analyzed.
