What are co-enzymes?
Small inorganic substances (e.g. Zinc ions) that need to be present in addition to an enzyme to
catalyze a certain reaction.
pH, Temperature, Enzyme concentration, Substrate concentration and Inhibition are all
factors that affect what?
Enzyme activity
An increase in enzyme temperature means and increase in enzyme what?
Activity
If enzyme temperature becomes to high the bonds break and functional shape is lost, the enzyme
is then?
Denatured
Will enzyme reactions continue to occur if there is no substrate present?
No
Reactions that use organic products to react and create energy are called?
Exergonic Reactions
Energy requiring reactions are called?
Endergonic Reactions
The chemical energy in glucose transferred to other compounds (ATP), to be used by cells is the
definition for?
Cellular respiration
The usual source of energy for cellular respiration is?
Glucose
Glucose circulates in the blood-stream → diffuses across capillary walls → into tissue and
surrounding cells, this is the pathway of glucose
Cellular respiration
What are the two types of cellular respiration?
Aerobic and Anaerobic Respiration
True or False, Aerobic Respiration does not require oxygen?
False
True or False, Anaerobic Respiration does not require oxygen?
True
The three steps of Anaerobic Respiration are?
Glycolysis, Kerbs cycle and Electron transport
Electron transport involves the reactions of what?
Loaded acceptor molecules
Krebs cycle occurs in the what?
Mitochondria
What kind of reaction is Photosynthesis?
Anabolic
The process of converting energy of sunlight to chemical energy in sugars is called?
Photosynthesis
Photosynthesis is carried out in the?
Chloroplasts
Have an outer membrane and folded inner membrane called thylakoid membranes, joined to form
stacks of flattened disks, called grana, this is
Chloroplast
Light dependent and light independent are both stages of what?
Photosynthesis
Where does the light independent stage occur?
Stoma
List 3 inputs of the light independent stage of photosynthesis…
Carbon dioxide, ATP, NADPH
Light energy, water, ADP and NADP are all inputs in what photosynthetic stage?
Light dependent stage
Different ……… are used in plants to trap different wavelengths of light
Pigments
What part of the nervous system carries info away from the cell body to another neuron and
tissue?
Axon
True of false, the Synaptic terminal communicates with other neurons?
True
The three basic kinds of neurons found in the nervous system are?
Affector neurons, Effector neurons and connecting neurons
Where does the light independent stage occur?
