Assoli18 [71]

Answer:

The answer is FALSE.

Explanation:

Schizophrenia is a personality disorder that affects a person's ability to think, feel and behave clearly.

Although there is a very strong genetic component to schizophrenia, genes alone do not completely explain the illness. Rather it is believed that genes do not directly cause schizophrenia, but do make a person vulnerable to developing the disease alongside other factors such as the environment and altered brain chemistry and structure.

The graphic shows the citric acid cycle. A diagram of the citric acid cycle is shown. Acetyl C o A enters the citric acid cycle
vagabundo [1.1K]

Answer:

It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.

Explanation:

Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)
