What’s the equation for photosynthesis
Carbon dioxide + water > Glucose + oxygen
CO2 + H2O > C6 H12 O6 + O2
What is the equation for aerobic respiration
Glucose + Oxygen > Carbon dioxide + water
C6 H12 O6 + O2 > CO2 + H2O
What is the equation for aerobic respiration in muscles
Glucose > lactic acid
What’s the equation for anaerobic respiration in plants and yeast cells
Glucose > ethanol + carbon dioxide
How does respiration in cells take place to transfer energy
Aerobically (using oxygen) or Anaerobically (without oxygen)
The energy transferred by respiration is
All the energy needed for a living process
Anaerobic respiration and used cells is called
Fermentation
During exercise the human body reacts to increase
The demand for energy
The heart rate breathing rate and breath volume increase during exercise. Why?
To supply the muscles with more oxygenated blood
Blood flowing through the muscles transports lactic acid to?
The liver
When lactic acid is transported to the liver where is it converted back into
Glucose
What is oxygen debt
It is the amount of extra oxygen in the body after exercise to react with the accumulated lactic acid and remove it from the cells
Define metabolism
Metabolism is the sum of all the reactions in a cell or body
The energy is transferred by respiration in cells used by what
The organism
The transfer of energy by respiration in cells is used by organisms for what
For the enzymes to control the process of metabolism and synthesizing new molecules
How can oxygen production be used to show the rate of photosynthesis
Measure the volume of oxygen produced in a given time
Or
When more oxygen is produced in a given time the rate of photosynthesis is faster
what do organisms need energy for
Chemical reactions to build larger molecules
movement
keeping warm
When insufficient oxygen is supplied what happens
Anaerobic respiration takes place in muscles
What is the process of photosynthesis
Endothermic
A product of photosynthesis is glucose. which of the following is not a product in photosynthesis
A. Respiration
B. For making amino acids
C. For making cellulose
D. Transpiration
D. Transpiration
What type of molecule is formed from combining glucose molecules with nitrate ions
Amino acids
Which organ converts lactic acid into glucose
The liver
What is the sum of all reactions that happen in a cell or body known as
Metabolism
What type of respiration transfers the most energy
Aerobic respiration
