Answer:
Cellular respiration continues in the mitochondria of the cell with the Krebs cycle and the electron transport chain.
Explanation:
The Krebs cycle is an important part of the cellular respiration process where —from energetic substrate such as carbohydrates, lipids and eventually proteins— Acetyl-CoA is obtained, whose oxidation produces energy in the form of ATP.
Both cellular respiration and Krebs cycle reactions occur in the mitochondria of the cells of aerobic organisms and, in conjunction with the electron transport chain, have a yield of 24 molecules of ATP for every molecule of glucose entering the system.
Cellular respiration continues in the mitochondria of the cell with the Krebs Cycle and the Electron Transport Chain. The Krebs Cycle metabolizes pyruvate molecules from glycolysis to produce ATP, NADH, and FADH2. These molecules are then used in the Electron Transport Chain, which uses oxygen as the final electron acceptor to create more ATP.
The blank in your statement 'Cellular respiration continues in the mitochondria of the cell with the _____________ cycle and the electron transport chain' is filled by the Krebs Cycle, also known as the Citric Acid Cycle or the Tricarboxylic Acid (TCA) Cycle. During this cycle, pyruvate molecules generated during glycolysis are metabolized by enzymes in the mitochondria, leading to the production of ATP, NADH, and FADH2. These energy-rich molecules are then utilized in the Electron Transport Chain (ETC).
The ETC is the final stage of aerobic respiration that uses free oxygen as the final electron acceptor for the electrons removed during the Krebs cycle. This results in the generation of water. In addition, electrons are rapidly passed from one component of the ETC to the next in a series of redox reactions that generate an electrochemical gradient. This gradient is key for the production of ATP through oxidative phosphorylation.

Answer:
C
Explanation:
Cellular respiration is best associated with the organelle mitochondrion.
Cellular respiration is associated with the mitochondria, where cells generate energy by breaking down glucose and other food molecules
Cellular respiration is best associated with the mitochondrion (option C). This is an important cellular process that enables cells to generate energy by breaking down glucose and other food molecules in the presence of oxygen. The mitochondria in our cells carry out this process, converting the chemical energy in food to a form the cell can use. While the Golgi apparatus, ribosome, chloroplast, and microtubule have crucial roles within the cell, they are not directly related to or responsible for cellular respiration.

cotyledons
endosperm
sepals
tendrils
Answer:
The correct answer would be cotyledons.
The cotyledons or seeds-leaf are defined as the primary leaf present in the embryo within the seeds of the higher plant.
After germination, the cotyledons may become the first leaves of the seedling.
The species of plants which possess one cotyledon are termed as monocotyledons whereas the species which possess two cotyledons are termed as dicotyledons.
Seed leaves, or cotyledons, are the first leaves to appear from a germinating seed and provide nutrients to the developing plant. Therefore, the correct answer is option a.
The other options mentioned are different parts or structures of a plant:
Therefore, the correct answer is option a.

proteins
lipids
nucleic acids
Answer:
Proteins.
Explanation:
Protein is one of the major biomolecule of living organisms and acts as a main building block of the body. Proteins are the polymers of amino acids.
Most of the enzymes present in living organism are made upof proteins. Antibodies made up of heavy and light chains are the constituent of proteins. Hormones like insulin, glucagon and epinephrine are proteinaceous in nature. Muscle contains protein like actin, myosin and nebulin. Hence, protein can act as antibody, enzyme, muscle and hormone.
Thus, the correct answer is option 2.
