Respiration Key Points Biology Part 2 Entry Test. Most important key points and cramming notes from f.sc Biology part 2 Respiration. There are two ways to breathe: with or without oxygen. What’s the difference? In the mitochondria, what happens?
How does photosynthesis give plants their energy? How does breathing change the gases in the blood? Find out with these MCQs about breathing! There are answer keys at the end, so you can see how well you did.Download/read online.
Respiration Key Points:
Chloroplasts and Mitochondria. In cellular respiration, in which free oxygen is turned into the water. This process is “aerobic cellular respiration,” both mitochondria and chloroplasts are necessary. Cellular respiration, also called oxidative metabolism, happens in all living things. Because Glucose is the main source of energy for all living things.
Respiration Main Points:
Glucokinase adds a phosphate group to glucose, which then moves from the cytoplasm to the mitochondria of the cell. Adenylate kinase and glyceraldehyde 3-phosphate dehydrogenase work together to make ATP. When NADH + H+ and FADH2.
To make pyruvate, which is a step in the process of glycolysis, break the high-energy bond glucose. ATP synthase in the mitochondria uses the energy from oxidative phosphorylation to turn ADP and P into 2 ATPs. When a molecule of glucose goes through glycolysis, it changes into which of these?
Biology Part 2 Cramming Notes:
Here are some important cramming notes on respiration key points of Biology part 2.
- In the medulla oblongata, the ventral medulla is an inspiratory center while the Dorsal and later Amelia is an expiratory center.
- A respiratory surface must have the following properties;
- Respiration should possess a large surface area for a sufficient amount of gaseous exchange. it should be vascularized.
- Lungs should have proper ventilation.
Some Conceptual Key Points Biology:
- The nose is the ONLY externally visible part of the respiratory system.
- The pharynx is the pan of both the digestive and respiratory systems.
- The trachea serves as an air canal and also a pan of the respiratory system. IA The length of the Trachea is 12cm & its width is 2cm.
- Incomplete rings that open towards the back.
- The trachea divides into right and left bronchi. The right bronchus has a larger diameter and is shorter than the left bronchus.
- Bronchioles are located at the end of bronchi and terminate in the Alveoli.
- Bronchioles are 1mm or less in diameter. Their walls consist of ciliated cuboidal epithelium and a layer of smooth muscle.
- Bronchioles have no cartilaginous plates.
Additional Explanatory Notes:
- The walls of the alveolus are 0.1 um thick.
- There are over 700 million alveoli present in the lungs, representing a total surface area of 70-90 m’.
- There are approximately 350 million alveoli in each lung.
- The wall of the alveoli has a layer of squamous epithelium cells.
