QuestionAnswer
Reactions that occur spontaneously and release energy are? exergonic
Name 3 facts about enzymes are highly specific and work on only a limited number of substrates. speed up chemical reactions within a cell The shape of the enzyme is important in it’s function.
What does ATP do? links exergonic and endergonic reactions in the cell. is the energy currency of the cell. is produced in the light-dependent reactions of photosynthesis.
Energy is released from the ATP molecule when _____is cleaved off. Phosphate
The energy required to begin a biological reaction is______? lowered by enzymes.
All steps of glycolysis occurs in the ________? Cytoplasm
By the end of aerobic respiration, the carbons that started in glucose are released as _____? Carbon Dioxide
What breaks down glucose to pyruvate? Glycolysis
The Kreb’s cycle (citric acid cycle) takes place in the ? Mitochondria
When glucose is used as the energy source in aerobic respiration, the largest amount of ATP is produced in? Electron transfer phosphorylation
The total number of ATP produced per glucose by aerobic respiration in animals is? 36
The total number of ATP produced per glucose by alcohoic fermentation (anaerobic) is ? 2
Which of the following is true about anaerobic respiration? It does not require oxygen
In aerobic respiration, the final acceptor of the spent electrons after the electron transfer phosphorylation steps is ? Oxygen
The carrier molecule (s) that picks up high energy electrons in the Krebs cycle and taxies them to the proteins involved in electron transport phosphorylation stage is ? Both NAD+ and FAD
When a photon of light excites chlorophyll, the chlorophyll molecule? Captures energy and transfers it to an electron
The non-cyclic electron flow of the light dependent step is photosynthesis involves? Both photosystem I and II
Which of the following is true of cyclic electron flow in photosynthesis? It produces only ATP
The carrier molecule that accepts the high energy electrons produced in the light dependent stage of photosynthesis and carries them to the dark stage reactions is? NADP+
The light-independent reactions of photosynthesis uses carbon dioxide to make glucose
Which of the following organic molecules can be broken down by cells to generate ATP? fats, carbohydrates and protein
Which of the following has stored potential chemical energy that can be used to make ATP? Glucose
The proteins in the ETP stages of aerobic respiration are located in the? Inner membrane of the mitochondria
In photosynthesis, oxygen is produced specifically _______ when electrons are taken from water to replace those lost by chlorophll a
The enzymes associated with the light-dependent reactions of photosynthesis are located ? in the inner (thylakoid) membrane of the chloroplast
What does the ETP do? ATP synthase uses the hydrogen ion gradient to make ATP/ A hydrogen ion gradient is produced across the inner membrane. Electrons from NADH enter the pathway.
Name 4 things associated with light-dependent reactions of photosynthesis. ATP, thlakoids, Chlorophyll, water is split to form oxygen
Which of the following is NOT PART during the light independent (dark) stage of photosynthesis? Carbon dioxide is required. Glucose is produced Water is split to form oxygen. ATP and NADPH is required in this step Water is split to form oxygen
During aerobic respiration, high energy electrons are stored on ______ and later used in _______ to make large amounts of ATP? NADH, ETP chain
In the first step of the light independent reactions, an enzyme adds _______ to the 5 carbon molecules? Carbon Dioxide
