Respiration
The organelle where aerobic respiration occurs.
Mitochondria
Give 2 examples of enzymes
catalase, protease, amylase, lactase
A group of organisms of the same species living together.
Population
The term used for a hidden trait only expressed when two copies are present.
Recessive
The site of fertilisation in humans.
Fallopian tube
The green pigment that absorbs light energy.
Chlorophyll
Differentiate between aerobic and anerobic respiration
Aerobic = oxygen
Anaerobic = No oxygen
What does optimal mean in relation to enzymes?
work their best at
The method used to estimate plant populations.
Quadrat
What are alleles?
Different forms of the same gene
The stage when the fertilised egg attaches to the uterus wall.
Implantation
The organelle where photosynthesis occurs and where its found
Chloroplast and cytoplasm
What are the two products produced in anaerobic respiration in yeast?
Ethanol and Co2
What is a catalyst?
A substance that speeds up a reaction without being used up.
The relationship where both organisms benefit.
Symbiotic/mutualism
what is the genotype of a heterozygous individual with dominant allele A.
Aa
Name the three seminal vesicles
Seminal Prostate, cowpers
The stage of photosynthesis where glucose is formed.
What is Phosphorylation?
ADP changes to ATP (addition of Pi)
The region of the enzyme where the substrate binds.
active site
The term for non-living environmental factors and one example
Abiotic factors, soil temp, air temp, water
The type of inheritance where both alleles are equally expressed.
Co - dominance
What is the function of the acrosome during fertilisation?
It releases digestive enzymes to break down the egg membrane so the sperm head can enter.
The molecule that accepts hydrogen during the light stage of photosynthesis.
NADP
What are the final products of stage 1? EXACTTT
2 Pyruvic acid, 2 ATP, 2 NADH
Explain the induced fit model
The enzyme model where the active site changes shape slightly to fit the substrate.
Define these 3 terms
Niche, Habitat, Conservation
Niche = Role of an organism
Habitat = Place where an organism lives
Conservation = Protection/ management of species/habitat/ecosystem/organisms
Mendel’s law stating that allele pairs separate during gamete formation.
Law of segregation
The correct order of early human development stages after fertilisation? (There are five)
zygote → morula → blastocyst → embryo → foetus
The equation for photosynthesis.
6CO2 + 6H2O→ C6H12O6+ 6O2
