The right answer is Pyruvate is split, citric acid is formed, coenzyme A is added

*Decarboxylation of pyruvate, is the reaction catalyzed by pyruvate dehydrogenase complex linking glycolysis to the Krebs cycle by converting pyruvate to acetyl-CoA.

*Citrate synthase condenses oxaloacetate and acetyl-CoA into citrate with release of coenzyme A. A transient intermediate, citroyl-CoA, is formed. The thioester linkage of acetyl-CoA is a high-potential hydrolysis bond. The coupling of the hydrolase and synthase activities makes the synthesis reaction thermodynamically possible.

*In the oxidative decarboxylation of α-ketoglutarate, the α-ketoglutarate dehydrogenase complex catalyzes the oxidative decarboxylation of α-ketoglutarate to succinyl-CoA with production of NADH + H + and evolution of CO2. It is a reaction similar to that converting pyruvate to acetyl-CoA catalyzed by the pyruvate dehydrogenase complex.

Whats the relationship between DNA,chromosomes,and genes?
Elina [12.6K]
DNA is a chain of nucleotides bonded together.  On that chain there are particular portions of it that the sequence of the nucleotide codes for particular proteins; this is known as a gene.  In eukaryotric cells, DNA is coiled around proteins such as histones to form chromatids which when two join at the centre by a centromere to form a chromosome.

Answer the following questions about the Corona virus:
True [87]

Answer:

where did they occur?

Retrospective investigations by Chinese authorities have identified human cases with onset of symptoms in early December 2019. While some of the earliest known cases had a link to a wholesale food market in Wuhan, some did not.

how did they started ?

What started as an epidemic mainly limited to China has now become a truly global pandemic. There have now been over 5,499,535 confirmed cases and 346,326 deaths, according the John Hopkins University coronavirus dashboard, which collates information from national and international health authorities. The disease has been detected in more than 200 countries and territories, with the US, Brazil and Russia experiencing the most widespread outbreaks, followed by the UK, Spain and Italy. In the UK, there have been 261,184 confirmed cases and 36,914 deaths as of May 25. The true number of infections and deaths is likely to be considerably higher.

How deadly are they?

Summary

Infection with the novel coronavirus can lead to coronavirus disease 19 . This can cause mild to severe symptoms. In some people, it leads to life threatening complications.

This article looks at the mortality rates of Coronavirus and the groups with the highest risk. It also explores what the illness does to the body and how it compares with the flu and severe acute respiratory syndrome (SARS).

All data and statistics are based on publicly available data at the time of publication. Some information may be out of date. Visit our coronavirus hub and follow our live updates page for the most recent information on the coronavirus outbreak.

When is it deadly?

Most people recover from coronavirus without needing hospital treatment.

coronavirus can be deadly for some people. Older adults and people with existing health conditions are more at risk of serious complications, which can be life threatening.

According to the World Health Organization (WHO), about 80% of people who develop the disease have mild to moderate symptoms and fully recover without needing treatment in a hospital.

Roughly 1 in 5 people experience serious illness.

Older people may develop more severe symptoms, as may people with ongoing health conditions, such as:

high blood pressure

cardiovascular disease

diabetes

chronic respiratory disease

cancer

Some severe coronavirus symptoms include difficulty breathing and a feeling of pressure in the chest.

coronavirus can also cause serious and sometimes fatal complications, including:

pneumonia

arrhythmia, which is an irregular heartbeat

damage to organs

multiple organ failure

sepsis

shock

respiratory distress syndrome

heart failure

Is there a vaccine?

To date, there are no specific vaccines or medicines for coronavirus. Treatments are under investigation, and will be tested through clinical trials

If you have mild symptoms and are otherwise healthy, self-isolate and contact your medical provider or a Coronavirus information line for advice.

Seek medical care if you have a fever, a cough, and difficulty breathing. Call in advance.

If you feel sick you should rest, drink plenty of fluid, and eat nutritious food. Stay in a separate room from other family members, and use a dedicated bathroom if possible. Clean and disinfect frequently touched surfaces.

Everyone should keep a healthy lifestyle at home. Maintain a healthy diet, sleep, stay active, and make social contact with loved ones through the phone or internet. Children need extra love and attention from adults during difficult times. Keep to regular routines and schedules as much as possible.

It is normal to feel sad, stressed, or confused during a crisis. Talking to people you trust, such as friends and family, can help. If you feel overwhelmed, talk to a health worker or counsellor.
