What is the difference between breathing and respiration?

Both breathing and respiration are required for all living organisms. Generally, breathing and respiration are often considered the same; however there is a big difference in the meaning of the two.

Breathing is when you consistently breathe in and out. It is the process of taking in oxygen and expelling carbon dioxide.

Respiration is a process where the body breaks down the oxygen, so that the cells in the body can use it.

 

Difference b/w aerobic & anaerobic activities:-

Aerobic:
1. occurs in presence of oxygen.
2. CO2 and water is produced
3. lot of energy is liberated (38 ATP)
4.occurs in plants' and animals' cells
5. C6H12O6 --> CO2 + H2O + ATP ( Energy)

Anaerobic:
1. occurs in absence of oxygen
2. Lactic Acid or Alchol is produced
3. relatively small energy is liberated (2ATP)
4. occurs in many anaerobic bacteria and human muscle cells.
5. in muscles, lactic acid is produced while bacteria as Yeast produces Alcohol (Ethanol)
6. C6H12O6 --> Lactic acid / C2H5OH + ATP

 

 

 

 

 

Both Plants and Humans are living organisms

Both Plants and Humans need things to keep them living

Plants - sunlight, Carbon Dioxide, and water
Humans - Calories, Oxygen, and water

Both produce substances that keep the other living

Plants produce oxygen which humans breathe in, in return humans breath out carbon dioxide for plants to create oxygen as a byproduct of Photosynthesis

Both Humans and Plants reproduce through sexual means by fertilization, but plants are hermaphrodites

Both Plants and Humans are multi-cell organisms, except plants are made of plant cells, and humans are made of animal cells

 

 

The main difference is that plant cells have a cell wall. The other is that they contain chloroplasts instead of hemoglobin molecules. Plants do photosynthesis and human cells do tissue respiration.

 

Exhaled air has a much higher percentage of CO2 compared to inhaled air; there is also a lower percentage of oxygen in exhaled air compared to inhaled air - but the difference is not so great as the body can only absorb a small amount of the oxygen which is in each lungful of air, so much of it gets breathed out again. CO2 content of the inhaled air is 0.04 %, whereas, of the exhaled air is 4 % (100 times) Humidity of the inhaled air is dependent on the geographical place.

 

Cockroaches

  • Cockroaches are broad and flat. They have a hard, protective, outer pair of wings, and a delicate inner pair for flying. Antennae are long and prominent. Chewing mouthparts are on the underside of the small head. Eyes are prominent and compound. Cockroaches range in color from light tan to dark brown. Some tropical species are brightly colored. Adult body size ranges from one-half to four inches long, depending on species.

Water Bugs

  • Water bugs range from flat to rounded, and smooth to covered with protuberances. Flying wings are kept under hard, protective wings covered in a waxy, waterproof cuticle. Antennae are small and tucked against the head. Eyes are also small, and absent in some species. Chewing and sucking mouthparts form a rostrum, or snout. Color ranges from tan to black, and some are bluish green or patterned. Sizes are similar to cockroaches. Members of the genus Lethocerus are very similar in appearance to cockroaches.

Habitats

  • Cockroaches are land animals. They colonize dark, compact spaces, preferring vertical areas only slightly wider than their own bodies. Water bugs are aquatic or amphibious. All water bugs spend at least part of their lives in freshwater, coming to the surface to breathe air. Some conceal themselves in mud, cling to plants, or are free-swimming. They can fly between bodies of water.

Feeding

  • Cockroaches are opportunistic, generalized feeders. They consume plant material and scavenge all types of plant and animal food. Many consume wood and wood products, such as paper and glues. They almost never kill any type of animal prey themselves. Water bugs are carnivorous and omnivorous predators. Some feed on the juices and soft parts of plants. Almost all kill animal prey, including other insects, small fish and amphibians.

Defense

  • Cockroaches defend themselves by hiding. Most run away from light. Sensory motion detectors help them flee anything that moves toward them. Water bugs defend themselves by hiding and playing dead, but some have weapons. Many water bugs use their rostrum to deliver a painful, stabbing wound. Their bite includes a poison that kills muscle tissue and causes blood poisoning and gangrene.

Social Behavior

Reproduction

    Male cockroaches sing a special song to attract females. Females carry their egg cases underneath or inside their bodies. In some species, the newly hatched young ride the mother. Male water bugs use a special dance at the water's surface to attract females. Males of some species carry the eggs on their backs. Each couple associates for an extended time during the breeding season. Each male mates with a single female but females may have multiple partners.

In exhaled air, carbon dioxide percentage is ten times higher than atmospheric co2 and oxygen being 16% instead of 21% which we find in the atmosphere. Plus there is some moistrure in the exhaled air.

Breathing and respiration

  • Breathing is a physical process of exchange of gases . No chemical reaction takes place while respiration is a chemical reaction of oxidation of food takes place .
  • Breathing takes place outside the cells while respiration takes place within the cells .
  • In breathing there is no release of energy while in respiration there is release of energy .

Aerobic respiration and Anaerobic respiration

  • When the breakdown of food (glucose) occurs with use of oxygen is called Aerobic Respiration . When the breakdown of food (glucose) occurs without using oxygen is called Anaerobic Respiration .
  • End products of aerobic respiration are carbon dioxide . End products of anaerobic respiration are alcohol and carbon dioxide .

Inhalation and Exhalation

  • The taking in of air rich in oxygen into our body is called Inhalation . The giving out of air rich in carbon dioxide is called Exhalation .
