what process converts a pyruvate into acetyl coA
glycolysis
krebs cycle
what is homeostasis
Maintenance of internal levels with boundaries
all chemical reactions that occur within the cell
atp is made from what
Adp
Adp plus pi group
the three stages of aerobic cellular respiration are 1. glycolysis 2.ETC 3. Krebs cycle 4.Net 34 ATP
the location of the light reaction in the cell is in the
what is one biological use of an isotope? and what is it?
isotope is the difference in valence electrons and the isotope can be used for cell dating
an isotope is a difference in the number of neutrons. one use for an isotope is to kill cancer tissue.
proteins are made up of C,H,O and amino acids, their function is ❌ and an example is dNA
on the ph scale, water is acid, because of its polarity neutral, because the pos h and neg o( acid, because of its polarity, neutral, because the pos h and neg o ), and why?
what process is this?
the location of the dark reaction in a cell
stroma
stomata
active transport
crenation of a cell is caused by a hypotonic solution
are hydrogen bonds strong or weak?
strong
weak
experimental group receives what?
placebo
treatment
neither
what is a community?
group of single species in an area
group of populations in the area
what is the placebo affect?
patients get better from non treatment
patients believe they're getting better so they feel better
photosynthesis is a transformation of solar energy into chemical energy stored in the bonds of proteins
what is osmosis
movement of water
permeability of water
polarity of water
hypertonic- having more solution than solute
phosphorylation is
is the addition of a phosphate group to a protein or other organic molecule
is the addition of a phosphate substance for an organic molecule
regulation is the use of positive and negative feedback mechanisms
taxonomy is the
which is not a step of natural selection
Varistion exists in every population
many species evolve from a single species
Environment is constantly changing
overproduction
which is not a characteristic of the kingdom, Monera?
unicellular
eukaryotic
pathogenic
heterotrophic
the five kingdoms are monera, protozoa, fungi, animal, plantae
the definition of a double blind study is
placebo effect
only independent variable should be different
no one knows who gets placebo or medication
both a and c
which one of the following is not a reason why water is glorious?
cohesion and adhesion
hydrolysis and dehydration synthesis
buffer
ph
amino acids are bonded together by
hormones like insulin
peptide bond
nucleic acids denature in inopportune temps or ph
what is the difference between an experimental group and a controlled?
controlled receives placebo and experimental receives treatment
controlled receives treatment and experimental receives placebo
the three ways to improve an experiment are to increase the sample size, repeat without making any changes and decrease bias by operating a double blind study.
breaking bonds energy
the formula for cellular respiration is; glucose +6O2 ------> 6h2o+ 6co2
hydrolysis is the to separate molecules, and dehydration synthesis is the to create more complex molecules.
Ribosomes make or create proteins
Nuclear membrane surrounds the nucleus and allows for the passage of DNA
rough endoplasmic reticulum synthesizes proteins
cell membrane is permeable, only hydrophilic and contains proteins
golgi body packages and distributes
vacuoles and vesicles transport, store and protect the cell. plants use it for water holding for photosynthesis
lysosome digest foods, organelles, and cells
mitochondira is the site of anaerobic respiration
which one of these are membranous
dna
lysosome
centrioles
ribosomes
centrioles aid in moving fluids across cell surface
