Answer:
a. First Step: The sugars are broken down to simple glucose molecules and the proteins and lipids are broken down to acetyl-CoA molecules. No energy is produced in this first step.
b. Second Step: Glycolysis converts the glucose to two molecules of pyruvate. Six ATP molecules are produced in this step.
c. Third Step: Oxidation of each pyruvate produces two molecules of acetyl-CoA. Six ATP molecules are produced in this step.
d. Fourth Step: Two acetyl-CoA molecules go through the Krebs (citric acid) cycle. Twenty-four ATP molecules are produced through this process.
e. All of the above steps are part of the break down of the candy bar's macromolecules.
Explanation:
Answer:
<em>photosynthesis utilizes carbon dioxide and water in the presence of light to produce glucose and oxygen, whereas respiration uses oxygen and glucose to power the activities of the cell.</em>
Answer:
sedimentary rock
Explanation:
the process of deposition refers to rock and soil depositing itself onto a landform and hardening into rock, specifically sedimentary rock.
Answer:
1 and 5,
2 and 6,
3 and 4
Explanation:
Intestinal phase: stomach empties and decreases secretions
The intestinal phase is the phase where stomach empties its contents(chyme) and decreases secretion. In this stage the duodenum responds to arriving chyme and moderates gastric activity through hormones and nervous reflexes.
The Chyme is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum.
Gastric phase: stomach secretes juice and mixes food into chyme
The gastric phase is a period in which swallowed food and semi-digested protein ( peptides and amino acids ) activate gastric activity which secretes juice and mixes food into chyme. About two-thirds of gastric secretion occurs during this phase.
Cephalic phase: prepares stomach for arrival of food
The cephalic phase of digestion is the gastric secretion that occurs prior to when food enters the oral cavity. Cephalic phase result from the ignition of visual, olfactory, and auditory inputs to the brain and also induce anticipatory responses i.e prepare the gastrointestinal tract for the meal.
Answer:
r-selected species (e.g., American bullfrog)
Explanation:
The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
