Document Content and Description Below
Most of the cell membrane's specific functions are controlled by: Proteins Alcoholic Fermentation is a form of: Anaerobic Respiration Phagocytosis is a form of: Endocytosis Wha... t is a pyruvate? Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy, in one of two ways. What are the small spherical bodies within a cell where proteins are assembled according to genetic instructions? Ribosomes What is the structural and functional unit of life? The cell What is a prokaryotic cell? A cell that lacks a true nucleus and membrane-bound organelles What is a eukaryotic cell? A cell that contains a nucleus and membrane-bound organelles What is cellular respiration? A catabolic pathway for the production of ATP, in which sometimes oxygen is consumed as a reactant along with an organic fuel. At times, the process proceeds without oxygen, but this is less efficient. What is anaerobic respiration? A form of cellular respiration that does not involve oxygen. What is aerobic respiration? Form of cellular respiration which requires oxygen to generate energy. Name the four types of transport that allow small molecules to move across the cell membrane: Diffusion, Osmosis, Active Transport, and Passive Transport. Prokaryotes often reproduce by: Binary Fission What is binary fission? A form of asexual reproduction in which the parent divides into two identical halves. What is cytokinesis? The division of cytoplasm into two identical daughter cells, which occurs during the telophase stage of mitosis. What is a haploid cell? A cell that contains one set of chromosomes What is a diploid cell? A cell that contains two sets of chromosomes What is chromatin? The substance of which eukaryotic chromosomes are composed, consisting of mostly proteins, DNA, and RNA. What is a centriole? a cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division. What is a chromosome? A structure carrying genes is a linear sequence, found in the nucleus, consisting of DNA and protein. [Show More]
