Conversion of 1 mol of acetyl-CoA to 2 mol of Co2 and CoA via the citric acid cycle results in the net production of 12 mol of ATP.

<h3>What is acetyl-coA?</h3>

Acetyl-CoA is produced in the mitochondrial matrix by oxidative decarboxylation of pyruvate from glycolysis, oxidation of long-chain fatty acids, or oxidative degradation of specific amino acids. The acetyl-CoA is then oxidized for energy production in the TCA cycle.

Mitochondrial enzymes are used in the citric acid cycle. The acetyl group of acetyl-CoA is fused with oxaloacetate in the first phase, which is mediated by citrate synthase. Citrate is formed as a result of the release of CoA-SH and heat. Dehydration and rehydration convert citrate to isocitrate.

pdf The effects of cannabis use during pregnancy on low birth weight and preterm birth: a systematic review and meta-analysis
alexandr1967 [171]

Findings In this meta-analysis of 16 studies involving 59 138 patients, maternal marijuana use during pregnancy was linked to a higher risk of preterm births and admission to neonatal intensive care units as well as a decrease in the average birth weight, the 1-minute Apgar score, and the babies' head circumference.

Birth weight, gestational age at delivery, small for gestational age (defined as less than the fifth percentile fetal weight for gestational age), preterm delivery (defined as before 37 weeks' gestation), admission to the neonatal intensive care unit (NICU), Apgar score at 1 minute, Apgar score at 5 minutes, the incidence of an Apgar score less than 7 at 5 minutes, fetal head circumference, a rate of preterm delivery, gestational age at delivery, birth weight.

A quantitative, formal, epidemiological study method known as a "meta-analysis" is used to carefully evaluate the findings of earlier research in order to draw conclusions about that body of work. The study is typically—but not always—based on randomized, controlled clinical trials. In order to find the answers to a particular topic, a systematic review makes an effort to compile all accessible empirical studies. The statistical method of assessing and combining data from numerous related studies is called a meta-analysis.
