Question

during glycolysis, one molecule of glucose is broken down into which of the following? two molecules of carbon dioxide two molecules of pyruvate two molecules of water two molecules of oxygen which of the following organelles is responsible for packaging and distributing proteins? golgi apparatus lysosome vacuole nucleus which of the following is not a phase of mitosis?* prophase metaphase telophase cytokinesis

Explanation:

• First question: Glycolysis is the metabolic pathway that converts glucose into pyruvate. Carbon dioxide is produced in later stages of cellular respiration (like the citric acid cycle), water is a by - product in many reactions but not the main product of glycolysis, and oxygen is not a product of glycolysis (it is a reactant in aerobic respiration).
• Second question: The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. Lysosomes contain digestive enzymes, vacuoles store substances (like water, nutrients, or waste), and the nucleus is the control center of the cell (contains DNA).
• Third question: Mitosis has four main phases: prophase (chromosomes condense, nuclear envelope breaks down), metaphase (chromosomes line up at the equator), anaphase (sister chromatids separate), and telophase (nuclear envelopes reform). Cytokinesis is the process of cell division (division of the cytoplasm) which occurs after mitosis.

Answer:

• First question: two molecules of pyruvate
• Second question: Golgi apparatus
• Third question: Cytokinesis
