Answer: Pyruvate is further oxidized to acetyl CoA before it can enter the Krebs cycle.

Explanation: Pyruvate is a three carbon compound. Before pyruvate can enter the Krebs cycle, it must be oxidized to acetyl CoA and carbon dioxide. The acetyl CoA then enters the Krebs cycle.

This reaction is an oxidative decarboxylation, an irreversible oxidation process in which the carboxyl group is removed from pyruvate as a molecule of carbon dioxide, and the two remaining carbons become the acetyl group of acetyl CoA.

The overall reaction of oxidation of pyruvate to acetyl CoA is catalyzed by an enzyme known as pyruvate dehydrogenase complex.

i think that before the Krebs cycle begins, pyruvic acid, which has three carbon atoms, is split apart and combined with an enzyme known as CoA.

Sloan [31]

Answer:

A. multimodal and multiphasic

Explanation:

Hypnosis can be defined as a mental state that is trance-like and it is typically characterized by minimal peripheral awareness, vivid fantasy, highly focused attention (concentration) and an increased level of suggestibility.

Simply stated, hypnosis is a sleep-like state and as such can be used by psychologist or therapist to reduce the sense of pain, induce relaxation, strengthen certain behaviors etc.

Hence, one of the ways in which hypnosis can be administered by psychologists or therapists is through Hypnotherapy, which typically involves the use of hypnosis in psychotherapy to treat medical conditions such as depression, eating disorders, anxiety, post-traumatic stress disorder (PTSD).

The treatment for post-traumatic stress disorder (PTSD) can be described as multimodal and multiphasic because it is characterized by series of activities and it takes place in various phases.
