Which of the following statements is INCORRECT? The esophagus produces digestive enzymes. The esophageal mucosa consists of nonk
eratinized stratified squamous epithelium. At each end of the esophagus, the muscularis forms two sphincters the upper esophageal sphincter and the lower esophageal sphincter. The upper esophageal sphincter consists of skeletal muscle and the lower of smooth muscle. The esophagus secretes mucus and transports food to the stomach.
The incorrect statement is: the esophagus produces digestive enzymes.
The esophagus is a fibromuscular pipe organ for the food transport from the pharynx to the stomach. The food passes through the esophagus via peristaltic contractions (rhyttmic contractions of the smooth muscles that propagate in a wave down the pipe). The esophagus is one of the first components of the digestive system and the gastrointestinal tract that is involved in the process of swallowing.
Answer is: when the carbon atoms of the glucose molecule are broken apart in glycolysis and the Krebs cycle, result is a. CO2 and ATP.
In Krebs cycle aerobic organisms release stored energy through the oxidation of acetyl-CoA derived from glucose into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP).
Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase
