NASA has long studied the concept of a bioregenerative life support system, in which human astronauts could be supported by photoautotrophic organisms (e.g., plants and algae) in a sealed system that could allow long term space exploration and colonization, for example, a base on the moon or Mars.

Outside help is not allowed. 1. Assume a simple example of such a system containing astronauts (people) and plants. Considering their metabolic requirements, what are the inputs each would need in order to survive, and what are the outputs they would contribute to the other? 2. Considering the laws of thermodynamics, what overall input (from outside the system) would the system require in order to function? Please label your answers 1. and 2. and explain both parts fully and clearly.

A hormone is released into the bloodstream and spreads throughout the body. Although many cells respond to that hormone, a specific cell type making up a tissue shows no response. This is most likely because the cells making up that tissue ______. Copyright 2024 by Edmonds College Department of Biology. All rights reserved. Online sharing or distribution is prohibited.

A plasma cell is a type of B lymphocyte (white blood cell) that has differentiated and specialized to synthesize huge numbers of antibodies very quickly. The specific protein structure of the antibodies enables them to bind to and neutralize antigens that resulted in their production. Given their role, you might expect plasma cells to contain especially large amounts of ______. Copyright 2024 by Edmonds College Department of Biology. All rights reserved.

A white blood cell of your immune system uses phagocytosis to capture and engulf a bacterial pathogen. Once inside the cell, the vesicle (called a phagosome) containing the bacterium is fused with a ______, an organelle that contains digestive enzymes that help break apart the pathogen.

Mitochondria contain their own DNA and ribosomes for protein synthesis of a number of proteins they require. However, a larger number of proteins are actually coded for in the nucleus of the cell, are synthesized in the cytoplasm, and are then transported to mitochondria. Based on what you know about protein transport processes, how do you think these proteins most likely make their way to mitochondria? Copyright 2024 by Edmonds College Department of Biology.
