Autotrophs a - Study guides, Class notes & Summaries

TEAS Test Science Questions and Answers 2023 An organism with chloroplasts in its cells is probably. a. a heterotroph b. an autotroph c. an herbivore d. a primary consumer - ANS-B: Organisms that have chloroplasts in their cells carry on photosynthesis and are therefore autotrophs. Autotrophs make their own food.

Bacteria shapes - Cocci, bacilli, vibrios (comma shaped), spirilla (spiral), pleiomorphic (various shapes) adherence molecules to stick to surfaces - - mediated by pili, fibers of pilin proteins possess other proteins on their tips for sticking - a sex pilus is used for conjugation - some microbes use an extension of the cell envelope tipped by a "holdfast" of paysaccharides 3 parts of flagella - - filament - hook protein - basal body active transport - - all microorganisms active tr...

BIOL 172L EXAM 1 UH MANOA; Questions and Answers 100% Solved Endosymbiosis Correct answer Organelles originated when a single-celled organism engulfed another single-celled organism • Usually obligate: the survival of one depends on the other the process in which unicellular organisms engulf other cells, which will then function as organelles within the host cell. Studies of DNA sequencing suggest that green and red algae developed when heterotrophic eukaryotes engulfed cyanobacter...

AP Biology Exam Question and Answers Verified 100% A+ 2024, With Rationale. The resting membrane potential depends on which of the following? I. Active transport II. Selective permeability III. Differential distribution of ions across the axonal membrane A. III only B. I and II only C. II and III only D. I, II, and III D The resting potential depends on active transport (the Na+K+-ATPase pump) and the selective permeability of the axon membrane to K+ than to Na+, which leads t...

WVU Biology 102 Exam 2 Questions and Answers Already Passed What products from the light reactions move on to the Calvin cycle? ATP and NADPH If a thylakoid membrane was punctured so that its interior was no longer separated from the stroma, which of the following processes would be directly affected? the synthesis of ATP A photosystem is a collection of pigments arranged in the thylakoid membrane When electrons from PSII are passed on to the electron acceptor, they are replaced ...

BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...

Macronutrients - carbon, nitrogen, phosphorus, sulfur, oxygen, hydrogen, potassium, sodium, magnesium, calcium, and iron Micronutrients - manganese, zinc, cobalt, molybdenum, nickel, copper All organisms require - Carbon, Hydrogen, Oxygen, and electrons Autotrophs - Assimilate carbon from inorganic sources Heterotrophs - Assimilate carbon in preexisting organic form Phototrophs - Capture light energy to produce ATP Chemotrophs - Capture energy from oxidation of reduced organic ...
