Respiration And Photosynthesis Flashcards
Where do we get energy from
We get our energy from our food by a chemical reaction in our cells called respiration
Equation for aerobic respiration
Oxygen+glucose -> carbon dioxide + water + (energy)
Why do we need energy
We need energy to move, eat, learn, sleep breathe even just to keep ourselves upright
Which gas is used up in respiration
Oxygen
Which gas is a product of respiration
Carbon dioxide
Why would a glass jar steam up with condensation when we breathe in
Respiration takes place in our cells. Carbon dioxide and water are produced, travel in the blood and some of the water is removed when we exhale
Where do most of the reactions take place in aerobic respiration
Mitochondria
What is anaerobic respiration
It’s respiration without oxygen. It happens in the cytoplasm. Glucose is only partially broken down which means that only a small amount of energy is released
What is the equation for anaerobic respiration
Glucose -> lactic acid + energy
What is aerobic respiration
A lot of energy is released in aerobic respiration it’s just normal respiration
What happens when there is anaerobic respiration
There is an oxygen debt so the animal continues to breathe deeply until the oxygen is replaced the oxygen is then able to break down the lactic acid into harmless carbon dioxide and water
What is the equation for photosynthesis
Carbon dioxide + water -> glucose + sugar
Wax cuticle
Prevents too much water from being lost
Air spaces
Allows gases to pass into and out of the spongy cells
Palisade cells
Contain many chloroplasts and are on the upper part of the leaf to get as much light as possible for photosynthesis
