1.Why do bacteria need to hydrolyze starch outside of the cell in order to use it as a food source? Pls. give me more clarification with this, Thank you

Why do microorganisms like bacteria have to break up extracellularly in order to use it as a food source?
I need help on these cell growth questions 1. As the length of the cell increases, which increases more rapidly the surface area or the volume? Justify your response. The How does the Surface area to volume ratio change as the length of the cell increases? 2. 3. Assume that every cell requires a minimum of 1 unit of oxygen per um (unit volume of cells) every second to stay alive. 10 um bacteria cell versus a 100 um cukaryotic...
1. You need to design a drug that kills bacteria without harming human cells. Name 2 cell structures (Cell composition/ parts) that you would consider a potential "targets" for your drug. Briefly explain why you chose each structure. 2. based on your knowledge of certain type(s) organic molecules, why do you think cells have to be maintained at a constant temperature and pH. 3. Give two different examples of using cell wall structure to tell different organism apart.
Hey guys I need help with homework. Certain amino acids are more energetically expensive than others (tryptophan versus glutamate). Thus, when proteins are moved to the cell surface, extended outside the surface, or secreted out of the cell, there is a potential harm. Why is this potentially harmful, and what adaptations do bacteria have for this potential loss? Give an example.
Why would a bacteria cell benefit from expressing the lac operon only in the presence of lactose? 1. The cell benefits by limiting the energy spent on the expression of the lac operonA. 2. The cell needs the lac operon to be expressed in order to obtain energy from lactose. 3. The cell doesn’t benefit, it would be better if the lac operon were expressed all of the time. 4.The production of lac operon proteins requires energy, but their production...

Chapter 4(microbiology) 1. What are the shapes and arrangements of bacteria cells? 2. Why is it important to be able to identify the shape and arrangement of an unknown bacterial sample? 3. Differentiate between eubacteria and archaebacteria. 4. What are the differences between eukaryotes and prokaryotes? 5. Why would a microbiologist care about those differences? Be specific. 6. What are the basic parts of a prokaryote? (the parts found in all bacteria) 7. How do the cell walls of Gram...

1.Discuss the use of ATP as the energy currency of the cell (include in your discussion the types of work performed by the cell) 2. Discuss ATP synthesis and ATP hydrolysis; How do cells obtain the energy to synthesize ATP? Why do cells hydrolyze ATP? What do cells do with released energy obtained from the hydrolysis of ATP? 3. Discuss oxidation & reduction and the role of electron transfer in ATP synthesis • discuss the role of NAD+ and FAD...
NEED HELP BY TONIGHT PLEASE!!! Please help me, I am deeply confused in this class and trying so hard to understand. Please give detailed answers. I know some of these might be confusing but your help will really help me learn. The teacher requires very very detailed answers and he gives nearly no (and I mean literally nearly zero) partial credit so I'm dying here. Thank you sooooooo much, you have no idea. Also, I am nearly leaglly blind and...
