Have you checked your text?
I've looked back over my notes and listened to the class lecture 3 times.
To find the correct answers for each question, let's go through them one by one:
1. During which stage of cellular respiration is most ATP made?
To answer this question, we need to know which stage of cellular respiration produces the most ATP. The options are:
A. Glycolysis
B. Chemiosmosis
C. Electron Transport Chain
D. Citric acid Cycle
The correct answer is C. Electron Transport Chain. This is where most of the ATP molecules are generated through oxidative phosphorylation.
2. The anticodon is part of a(n) ____ molecule and the codon is part of a(n) ___ molecule?
In this question, we need to identify which molecule contains the anticodon and which molecule contains the codon. The options are:
A. tRNA...rRNA
B. tRNA...mRNA
C. mRNA...tRNA
D. mRNA...rRNA
The correct answer is B. tRNA...mRNA. The anticodon is found on tRNA molecules, and the codon is found on mRNA molecules. Anticodons and codons are complementary sequences that help in the translation of genetic information.
3. Which phase of cellular respiration does not require oxygen?
This question asks us to identify the phase of cellular respiration that can occur without the presence of oxygen. The options are:
A. glycolysis
B. Krebs cycle
C. Chemiosmosis
D. Electron Transport Chain
The correct answer is A. glycolysis. Glycolysis is the initial step of cellular respiration and can take place in the absence of oxygen, producing two molecules of ATP.
4. A high concentration of H+ (protons) is found in the?
To determine where a high concentration of H+ ions is found, we need to consider the cellular compartments. The options are:
A. Nucleus
B. Mitochondrial Intermembrane Space
C. Mitochondrial Matrix
D. Cytoplasm
The correct answer is B. Mitochondrial Intermembrane Space. During cellular respiration, the Electron Transport Chain pumps H+ ions into the intermembrane space, creating a high concentration of protons.
5. Which process/event is correctly matched to the phase in which it occurs?
To find the correct match between a process/event and the phase, we need to understand the different phases of gene expression. The options are:
A. amino acids are joined together: Transcription
B. tRNA delivers amino acids: Translation
C. RNA polymerase binds to promoter: elongation
D. initiation: translation
The correct answer is B. tRNA delivers amino acids: Translation. During translation, tRNA molecules deliver amino acids to the ribosome based on the codons of the mRNA molecule.
6. Atp synthase is an enzyme in the.
To determine where ATP synthase enzyme is located, we need to consider cellular compartments. The options are:
A. NUCLEUS
B. CELL MEMBRANE
C. MITOCHONDRIAL MEMBRANE
D. MITOCHONDRIAL MATRIX
The correct answer is C. MITOCHONDRIAL MEMBRANE. ATP synthase is embedded in the inner mitochondrial membrane and plays a crucial role in ATP production during cellular respiration.
7. Two molecules of ____ are produced by glycolysis. Each molecule has ____ carbons.
To find the correct molecules produced by glycolysis and the number of carbons they contain, we need to recall the details of glycolysis. The options are:
A. Oxaloacetate...4
B. Citrate...3
C. Pyruvate...3
D. Acetate...4
The correct answer is C. Pyruvate...3. During glycolysis, glucose is broken down into two molecules of pyruvate, each containing three carbons.
8. Oxaloacetate combines with acetyl CoA at the beginning of.
To identify the process where oxaloacetate combines with acetyl CoA, we need to consider the different stages of cellular respiration. The options are:
A. Electron transport chain
B. Glycolysis
C. Transcription
D. Krebs cycle
The correct answer is D. Krebs cycle. In the Krebs cycle, the combination of oxaloacetate with acetyl CoA initiates a series of reactions leading to the production of ATP and electron carriers.
9. Which nitrogenous base is not present in ribonucleic acid?
To identify the nitrogenous base absent in ribonucleic acid (RNA), we need to recall the different bases found in RNA. The options are:
A. Fuanine
B. Uracil
C. Cytosine
D. Thymine
The correct answer is D. Thymine. Thymine is found in DNA, whereas RNA contains uracil instead of thymine as one of its bases.
