B4 - Bioenergetics Flashcards
What does photosynthesis produce
Glucose
What does photosynthesis use to make glucose
Light
What is the word equation for photosynthesis
Carbon dioxide + water ——Light—— glucose + oxygen
What is the symbol equation for photosynthesis
6CO2 + 6H2O —— light —— C6H1206 + 6O2
What are the five main ways plants use glucose
For respiration, making cellulose, making amino acids, it is stored as oils and fats, and it is also stored as starch
What do limiting factors do to photosynthesis
They affect it
How can the rate of photosynthesis be affected
The intensity of the light, Concentration of CO2 and the temperature
What does limiting factor mean
It’s stopping photosynthesis from happening any faster
What happens when the temperature is to high
The enzyme denatures
What does oxygen production show
The rate of photosynthesis
What can be used to measure the effect of light intensity
Canadian pondweed
What does the inverse square law link
Light intensity and distance
How can you create the ideal conditions for farming
Artificially
What is the most common way of artificially creating the ideal conditions for farming
A green house
What does a green house help do
Trap the suns heat
What is respiration
The process of transferring energy from glucose
What are the three ways organisms use the energy transferred by respiration
To build larger molecules, to allow muscles to contract, keep body temperature steady
What is metabolism
All the chemical reactions in an organism
What does aerobic respiration need
Oxygen
What is the word equation for aerobic respiration
Glucose + oxygen ————— carbon dioxide + water
What is the symbol equation for aerobic respiration
C6H12O6 + 602 ——————— 6CO2 + 6H2O
When is anaerobic respiration used
When there isn’t enough oxygen
What is the word equation for anaerobic respiration
Glucose ———————— lactic acid
How else can plants and yeast cells respire
Without oxygen
What is the word equation for anaerobic respiration in plants and yeast cells
Glucose ———————— ethanol + carbon dioxide
What is anaerobic respiration in yeast cells called
Fermentation
What does anaerobic respiration lead to
An oxygen debt
What are two effects of exercise on the body
Increased breathing rate and increased heart rate
How can you measure the effects on the body
For breathing rate you can count the number of breath before and after exercise and for heart rate check pulse before and after exercise
