Mr O’neill’s Biology Eca Prep Ultimate

7.6.1 State that metabolic pathways consist of chains and cycles of enzyme-catalysed reactions. – Enzymes catalyse chains or cyclic rings of reactions where one substrate forms a new product to be used in the next step of the reaction. Each step is catalysed by a specific enzyme until end product formation.
70 mV – resting membrane potential (inside of cell is negative compared to outside)
mutations – Random errors in gene replication that lead to a change in the sequence of nucleotides. The source of all genetic diversity.
Habitat – The general place where an organism lives
chromatid – a duplicated chromosome attached to a centromere
Monosaccharides – Monnosaccharides have the empirical formula CH2O and have between three and seven carbon atoms. They include glucose, galactose and fructose whiach are all hexose sugars.
(T/F) If glucose is unavailable, the body can use carbohydrates, fats, and proteins to create energy – True
What are the 7 steps of the Scientific Method? – 1. Observe
2. Research
3. Form a hypothesis
4. Test the hypothesis
5. Analyze results and draw conclusions
6. Report your findings
7. Conduct more research
Complement of T (Thymine) – A (Adenine)
The abnormal growing together of two peritoneal surfaces that normally are separate is called a(n)
connective tissue – Connects, supports, transports, or stores materials in the body.
autonomic nervous system – Part of the peripheral nervous system that controls automatic, or unconscious functions.
Solution – mixture of two or more substances in which the molecules of the substances are evenly distributed
Mutualism – the relation between two different species of organisms that are interdependent
Phospholipid – A lipid that contains phosphorus and that is a structural component in cell membranes
What is the buffer for? – helps prevent shifts in pH.
activation energy – The amount of energy needed to push the reactants over an energy barrier.
The аbnоrmаl grоwing tоgether of two peritoneаl surfaces that normally are separate is called a(n)
Ribosomes – A cell organelle composed of RNA and protein; the site of protein synthesis.
amino acid – Small carbon compound joined by peptide bonds; building block of proteins.
Level of organization – In ecology, one of the hierarchical groups into which the parts are ordered: individual, population, community, ecosystem, and finally the biosphere.
homeostasis – maintaining a stable internal environment (plasma membrane's main job)
