2. Structure and function in living organisms (f and g) Flashcards
How is ATP produced?
Respiration
What does ATP do?
Provides energy for cells
What is aerobic respiration?
Breakdown of Glucose in the presence of Oxygen to produce Carbon Dioxide and Water to release energy; occurs in the Mitochondria of the cell
What is anaerobic respiration?
Breakdown of Glucose in the absence of Oxygen to produce Lactic acid (and small amounts of energy) in humans, and Carbon dioxide and Ethanol (and small amounts of energy) in yeast and plants; occurs during exercise and causes cramps in humans (due to build-up of Lactic acid)
What is the equation for aerobic respiration?
Glucose + Oxygen → Carbon Dioxide + Water
What is the equation for anaerobic respiration in humans?
Glucose → Lactic Acid
What is the equation for anaerobic respiration in yeast and plants?
Glucose → Ethanol + Carbon Dioxide
What is the word equation for aerobic respiration?
Glucose + Oxygen –> (energy released) Carbon Dioxide + Water
What is the balanced equation for aerobic respiration?
C6H12O6 + 6O2 –> (energy released) 6CO2 + 6H2O
Describe the structure of the ribs in the thorax:
The bone structure that protects internal organs including the Lungs
Describe the structure of the intercostal muscles in the thorax?
Muscles between the Ribs that move ribcage during inhalation and exhalation
Describe the structure of the diaphragm in the thorax:
Sheet of muscle at bottom of Thorax that changes the thoracic volume during inhalation and exhalation
Describe the structure of the trachea in the thorax:
Windpipe that connects the Mouth and Nose to the Lungs
Describe the structure of the bronchi in the thorax:
Thick tubes that divides into two Bronchi inside Lungs - one Bronchus for each Lung
Describe the structure of the bronchioles in the thorax:
Bronchi will split to form thinner tubes called Bronchioles that are connected to Alveoli
