Answer:

  • <u>axonemal microtubules</u>: (G) is in cilia and flagella
  • <u>nucleation</u>: (H) formation of tubulin oligomers
  • <u>treadmilling</u>: (R) assembly and disassembly on opposite ends of the same filament
  • <u>desmin</u>: (T) keeps muscle myofibrils in register
  • <u>EB1</u>: (I) binds to microtubule plus ends
  • <u>ARP2/3 complexes</u>: (P) nucleates actin filament branches
  • <u> myosin subfragment 1 (S1</u>): (O) decorates actin filaments
  • <u>tropomodulin</u>: (J) prevents loss of subunits from filament minus ends  
  • <u>gelsolin</u>: (S) breaks and caps actin filaments
  • <u>microvilli</u>: (N) increase cell surface
  • <u>filamin</u>: (K) connects crisscrossing actin filaments into 3D networks
  • <u>phosphoinositides</u>: (L) binds to profilin and CapZ
  • <u>MAPs</u>: (F) stabilizes and organizes microtubles
  • <u>plectin</u>: (C) crosslinks microtubles to intermediate filaments
  • <u>lamin</u>: (E) forms scaffold underlying nuclear envelope.

Explanation:

  • Axonemal microtuble: an axoneme is a microbule based cytoskeleton structure of a eukaryotic cilium or flagellum. It provides motility, and also gives support to the structure.
  • nucleation: it is a process where interaction of several tubulin molecules lead to the formation of microtubules seed. This process occurs spontaneously in purified tubulin solutions.
  • treadmilling: is a phenomenon, that especially occurs in actin filaments and microtubules,where continuous removal of actin monomers from pointed ends of filament occur and their reincorporation at the other ends
  • desmin: it is a specific protein found in muscle that integrates sarcolemma, Z disk and nuclear membrane in sarcomeres and regulates sarcomere architecture
  • EB1: its a plus-end tracking protein that binds to plus end of microtules and modulates their dynamics and interactions with intercellular organelles.
  • ARP2/3 complex: its a seven-subunit central actin nucleator that binds  to the side of filament to promote new filament growth as a branch thus forming a complex actin network.
  • myosin subfragmnet (S1): S1 is the head fragment of myosin globular heads, that contains the ATPase and actin-binding activities of myosin.
  • tropomodulin: it is a protein that binds and caps the pointed ends(or minus ends) of actin filaments thereby regulating its length in muscle cells as well as non muscle cell.
  • gelsolin: is an actin binding protein that binds and caps actin filament(responsible for assembling and disassembling of filaments)
  • microvilli: found in the apical surface of epithelial cells or the stereocillia, spine like protrusions, that increase the cell surface area for diffusion upto 100 times.
  • filamin: is an actin binding protein that holds two filaments at large angles.
  • phosphoinositides: it regulates the activities of many actin binding proteins and have the tendency to bind with profilin and CapZ(its a capping protein that caps the barbed ends of actin filament)
  • MAPs: microtubules associated protein or MAPs binds to and stabilizes microtubules lattice. MAPs have repeating domains that allow eash MAP molecule to associate with more than one tubulin dimer.
  • plectin: a structural protein of the cytoskeleton that maintains tissue integrity
  • lamin: are fibrous protein of type V intermediate filaments that provide structural function and transcriptional regulation in the cell nucleus.

What are the advantages and disadvantages of using renewable and nonrenewable energy resources? Use evidence from the lesson and
timofeeve [1]

Answer:

The answer to this question is given below in this explanation section.

Explanation:

Advantages of renewable energy resources:

Using renewable energy over fossil fuels has a number of advantages.Here are some of the top benefits of growing green.

  • Renewable energy won't run out:

Renewable energy technologies use resource straight from the environment to generate power.These energy sources include sunshine,wind,tides,and biomass,to name some of the more popular options.

  • Maintenance requirements are lower:

In most cases,renewable energy technologies require less overall maintenance  than generators that use traditional fuel sources.This is because generating technology like solar panels and wind.

  • Renewables save money:

Using renewable energy can help you save money long term.Not only will you save on maintenance costs,but on operating cost as well.When you are using a technology but generates power from from the sun wind team natural processes.

  • Renewable energy has numerous health and environmental benefits:

Renewable energy resources emit little to no greenhouse gases or pollutants into the air.

  • Renewable lower reliance on foreign energy sources:

With renewable energy technologies you can produce energy locally.The more renewable energy you are using for power needs.

Disadvantages of renewable energy:

  • Higher upfront cost:

You can save money by using renewable energy the technologies are typically more expensive upfront by traditional energy generators.

  • Intermittency:

Through renewable energy resources are available around the world many of these resources are not available year around.

  • Storage capabilities:

Because  of this intermittency of some renewable energy resources there a high need of energy storage.

  • Geographic limitations:

The united states has a diverse geography with varying climates topographies vegetations and more.

How does ATP release energy?
Anna71 [15]

Answer:

While ATP itself doesn't just generate energy from being present it for the most part does that probably seems confusing so I will clarify. ATP is a highly unstable molecule and without the assistants of anything its bonds will break. So you start with ADP once chemiosmosis is complete specifically the phosphorylation portion of it, Adenosine diphosphate because adenosine triphosphate. Basically a phosphate molecule is shoved on to ADP making ATP this last molecule is easily broken off, as I previously explained, releasing energy.

A simple explanation is what follows. When ATP loses a phosphate molecule becoming ADP energy is released.
