- enzyme-mediated chemical reactions take place when a substrate molecules bind to the ___ ___ of an enzyme
- a ___ ___ is a sequence of reactions occurring in an individual cell that are organized so that the product of one reaction becomes the substrate of the next
- What is the term used to describe the energy of a system that is available to do work?
- where does a substrate bind on an enzyme in order for a chemical reaction to take place?
- what molecule is a common energy source for living organisms?
- the activation energy is a barrier to the formation of products. How can this be overcome?
- with very few exceptions, all energy that enters biological systems ultimately comes from the ___
- Helicase, topoisomerase, DNA polymerase, primase, leading strand and lagging strand, DNA single-stranded binding proteins, ligase
- 1) Phosphate group 2) Sugar (Deoxyribose in DNA) 3) Base (G / C / A / T)
- Adenine (A) pairs with Thymine (T)Cytosine (C) pairs with Guanine (G)
- Nucleotides -> single strand -> double helix -> chromosome -> genome
- NAD+ (oxidized form) and NADH (reduced form) / FAD (oxidized form) and FADH2 (reduced form)
- Active site, substrates, enzyme-substrate complex, products, saturation
- 1) glycolysis 2) Acetyl CoA formation 3) Krebs cycle 4) electron transport chain
- Enzymes- lower the activation energy but are not changed or consumed by the reaction. They are reusable.
- Nucleus acid structure, DNA structure, chromosome structure
- Enzyme concentration, substrate concentration, temperature, pH, inhibitor concentration
- • glycolysis (anaerobic) = 2 ATP • Krebs cycle (aerobic) = 2 ATP • ETC (aerobic) = 34 ATP • 38 ATP's (theoretically) are produced per 1 molecule of glucose. • 30-34 ATPs are actually produced
- Which statement best describes a direct role of ATP in a paramecium?
- In cellular respiration, how much ATP is produced per molecule of glucose?
