Answer:
b) electron transport chain
Explanation:
During sprinting, muscles need a constant supply of ATPs (the energy currency of cells) to support the continuous movement. The electron transport chain is present in the inner mitochondrial membrane.
Oxidation of NADH and FADH2 through electron transport chain produces proton gradient across the membrane which in turn drives the synthesis of a large number of ATPs to support sprinting.
<h2>Answer </h2>
Lactic acid fermentation ocurrs in muscle cells when oxygen is in low supply
<u>Explanation</u>
The lactic acid fermentation in the muscles cell occurs when muscles work faster and it occurs due to the lack of supply of oxygen in the cell. The lactic acid fermentation is a type of aerobic respiration. The lactic acid formation is due to excessive exercise by individuals and oxygen which is essential for living, is less in the muscle which causes the feeling of burning in the muscles.
Answer is F: Facilitates the movement of particles across the cell membrane.
Types of proteins found in the cell membrane includes channel and carrier proteins, both which are involved in the process of facilitated diffusion where they help facilitate the movement of large or polar molecules across the membrane.
Answer: False.
Explanation:
A normal fault is a type of fault in which the hanging wall drop down in relative to the footwall. It is caused by tensional stress, when two block of rocks pull apart from each other. Normal fault normal happen in areas that are undergoing extension or stretching.
Reverse fault are caused by compressive stress.
<span>Along North American coasts, the algae responsible for formation of kelp-beds is Brown Algae. The brown algae (such as seaweed) forms an important part of the ecosystem in marine environments as both a food source and habitat. The formation and structure of the brown algae varies from environment, kelp beds and forests are harvested for human consumption.</span>
