Plants use photosynthesis
<span>In the presence of oxygen, one glucose molecule has the energy to make up to 38 ATP. The ATP production is determined by the following steps, (-2 ATP) glycolysis preparatory phase, (7-9 ATP) glycolysis pay-off phase, (5 ATP) oxidative decarboxylation of pyruvate and (20 ATP) Krebs cycle. One glucose which has 38 ATP hence was the summation of all the process mentioned that took place. All these process take place under the cellular function of cellular respiration.<span>

A plant that is unable to produce glucose will likely die.
<h3>WHAT IS PHOTOSYNTHESIS?</h3>
Photosynthesis is the process whereby green plants obtain their food using energy from sunlight.
The food molecules are in the form of an organic compound called glucose. The glucose is the source of energy for living cells.
This means that if a plant cell is unable to produce glucose, the plant will likely die because there is no source of energy for metabolic activities.

Answer:
This question lacks options, options are:
A) histamine
B) gastrin
C) secretin
D) ACh
The correct answer is C.
Hormones or paracrines that inhibit gastric secretion include <u>secretin
</u>.
Explanation:
Hormones pass into the blood that waters the digestive system, go to the heart, circulate through the arteries and return to the digestive system, where they stimulate the production of digestive juices. The hormones that control digestion are gastrin, secretin and cholecystokinin. Secretin is stimulated by intestinal acid at the duodenal level. Its effect inhibits gastric acid secretion, prostaglandin secretion and via somatostatin release. It decreases gastric emptying and stimulates bile and pancreatic bicarbonate secretion.
Answer: Positive feedback loop
Explanation:
Even before the food reaches the stomach (before ingesting it), the glands of the stomach mucosa begin to release its gastric secretion. The main characteristic of this secretion is acidity, as measured by pH (one of the physiological variables).
This acidity is a result of the presence of hydrochloric acid, which is part of the secretion composition. In addition to it, water, pepsinogen (which will give rise to the enzyme pepsin) and the intrinsic factor. The acid has a function of the protection of the entire system by eliminating microorganisms. It is also responsible for the activation of pepsin (which only occurs with acid pH), the enzyme that digests proteins containing the amino acids leucine or phenylalanine or tryptophan or tyrosine.
The concept of Positive feedback loop states that the body tries to increase the value of a variable (acidity, in the case of pepsinogen) when it is below its optimal value (called a point adjustment) and decreases this value when it is above optimal.
