body. Introduction Respiration is the physical process by which living organisms take in oxygen from the surrounding medium and emit carbon dioxide. The term respiration is also used to refer to the liberation of energy‚ within the cell‚ from fuel molecules such as carbohydrates and fats. Carbon dioxide and water are the products of this process‚ which is sometimes called cellular respiration to distinguish it from the physical process of breathing. Cellular respiration is similar in most organisms

Glycolysis (occurs in the cytoplasm) 1. One glucose is split into two pyruvates (C3H4O3). 2. 4 ATP are produced‚ but 2 endergonic reactions use up 2 ATP. 3. Glycolysis requires no oxygen‚ and occurs whether oxygen is present or not. 4

Measuring the rate of cellular respiration in yeast within different types of sugar Aim/Reasearch Question: How can the rate of cellular respiration be measured to find out if sucrose‚ dextrose‚ lactose‚ or maltose lets the yeast to respire more than others. Hypothesis: I think‚ dextrose yeast solution will respire the most number of bubbles because it is the simplest sugar to break. Materials: * Knut * Dropper * Graduated cylinder (100ml) * Warm water * Yeast Solution

Explain how CO2 enters leaves. What environmental factors control stomatal movement? How are these factors related to physical and chemical properties that control the opening and closing of stomata? CO2 enters leaves through stomata‚ which are small openings in the leaves surrounded by guard cells. These stomata are responsive to light‚ so they open with natural light and close at night. One interesting environmental factor that can control stomatal movement is the overall level of CO2 in the

bioJared Kerr Chapter 7 Section 2 I. Aerobic Respiration a. Overview of aerobic 1. Aerobic respiration has two major stages; the Krebs Cycle and the electron transport chain. 2. In the Krebs cycle‚ the oxidation of glucose that began with glycolysis is completed. 3. In the electron transport chain‚ NADH is use to make ATP. 4. In prokaryotes the reactions take place in the cytoeol. 5. In eukaryotes the reactions take place in the mitochondria. 6. The mitochondrial

muscles through red blood cells; this is how muscles get the energy they need‚ to work. (2) Aerobic respiration is the way energy is released from glucose when working muscles contract and relax. Muscles normally work in pairs first one contracts (become shorter and wider) and the other relaxes (becomes longer and thinner) this is how they work when moving bones. (1) Formula for aerobic respiration Glucose + oxygen Carbon Dioxide + water (+ energy) Muscle fatigue and what causes

eat the plants‚ and take the carbon in the sugars‚ inside their cells they take the energy from the food‚ this is cellular respiration‚ which takes oxygen (product of photosynthesis) and makes carbon dioxide (also used in photosynthesis) ‚ it then gives energy by breaking down the food molecules‚ this is the link between the two. There are two types of cellular respiration; aerobic and anaerobic. Both use the same steps‚ where the sugar created during photosynthesis is broken down. (Audesirk‚ T
