CHAPTER II THEORETICAL FRAMEWORK This Chapter presents the Relevant Theories‚ Related Literature and Studies‚ Conceptual Framework‚ Hypothesis and the Definition of Terms used in the study. Relevant Theories There are two theories which are considered relevant in this study‚ namely: Goal Setting Theory of Motiviation by Dr. Edwin Locke (1990)‚ and Cognitive Learning Theory. Goal Setting Theory states that goal setting is essentially linked to task performance. It states that specific

the process is known as cellular respiration by which cells break down complex molecules‚ such as sugars‚ to release carbon dioxide. The complex chemical reactions of photosynthesis and cellular respiration help meet the energy needs of living things. (Cellular Respiration) In this experiment you will be testing the amount of carbon dioxide and oxygen produced or consumed during photosynthesis

Erasistratus’s model of the respiration and blood distribution is considerably more mechanical than Aristotle’s due to the technological advances that were thriving in Alexandria compared to Athens. Both scientists base their models of respiration and blood distribution in the body from technological-ladenness of observation. Erasistratus proposes that heart uses force propulsion to distribute air and blood throughout the arteries and veins. His concept focuses on “the filling towards what is being”

understand the process of fermentation of yeast in different concentrations of sucrose. The experiment worked with yeast and sugar (sucrose and glucose) to determine the rate of fermentation by testing the pressure of C02 in the test tube. The experiment tested the metabolic capability of yeast anaerobically meaning no oxygen was present (this was ensured by the thin layer of oil on the top of the solution). This means that the metabolic rate of the yeast could be determined by testing the pressure

Activity-Related Affect Activity-related affects are individual’s feelings towards the desired activity. “Activity- related affect consist of three components: emotional arousal to the act itself (act related)‚ the self-acting (self-related)‚ and the environment in which the action takes place (context related)” (Pender et al.‚ 2014‚ p. 37). If the individual enjoys the activity‚ they will continue it. However‚ if the activity is not enjoyed‚ the individual will most likely avoid it. S.M. has a

cellular respiration is oxygen and carbon dioxide. The process of cellular respiration is releasing energy from sugars using oxygen and the product is carbon dioxide and water and in the process‚ ATP is made that can then be used for cellular work. Oxygen is needed to be absorbed from the environment and into the organism’s blood so it can be transported to respiring cells. Carbon dioxide must be released into the environment from the organism’s blood. The formula for cellular respiration is:

pulse rate. Breathing is a type of respiration in animals. All plants and animals do cellular respiration. Respiration is the release of energy‚ which occurs in the living things’ cells. Cellular respiration is the use of glucose and oxygen to yield ATP which is usable energy. Glucose is broken down into glycolysis‚ which is then used to make ATP. ATP is the usable form of energy which allows organism to function. Almost all organisms do cellular respiration‚ others do anaerobic respiration. Cellular

and NAD+ is finite (limited). What happens to cellular respiration when all of the cell’s NAD+ has been converted to NADH? If NAD is unavailable‚ the cell is unable to conduct any processes that involve the conversion of NAD+ to NADH. Because both glycolysis and the Krebs cycle produce NADH‚ both of these processes shut down when there is no available NAD+. 5. If the Krebs cycle does not require oxygen‚ why does cellular respiration stop after glycolysis when no oxygen is present? When no
